Movie-Plot Threats at the U.S. Capitol

This would make a great movie:

Rep. Dan Burton, R-Ind., renewed his call for the installation of an impenetrable, see-through security shield around the viewing gallery overlooking the House floor. Burton points out that, while guns and some bombs would be picked up by metal detectors, a saboteur could get into the Capitol concealing plastic explosives.

The House floor, he pointed out, is the only room where all three branches of government gather to hear the president speak, as President Obama will do when he delivers his State of the Union address on Jan. 25.

Burton introduced the legislation in the past, but it’s gone nowhere. He’s hoping the tragic events of Saturday could help it win more serious consideration by the Republican leadership.

“I think the risk is there,” Burton told The Washington Examiner. “The threat is more now than it has ever been.”

"Architecture of Fear"

I like the phrase:

Németh said the zones not only affect the appearance of landmark buildings but also reflect an ‘architecture of fear’ as evidenced, for example, by the bunker-like appearance of embassies and other perceived targets.

Ultimately, he said, these places impart a dual message—simultaneously reassuring the public while causing a sense of unease.

And in the end, their effect could be negligible.

“Indeed, overt security measures may be no more effective than covert intelligence techniques,” he said. “But the architecture aims to comfort both property developers concerned with investment risk and residents and tourists with the notion that terror threats are being addressed and that daily life will soon ‘return to normal.'”

My own essay on architecture and security from 2006.

EDITED TO ADD (1/13): Here’s the full paper. And some stuff from the Whole Building Design Guide site. Also see the planned U.S. embassy in London, which includes a moat.

Full Body Scanners: What's Next?

Organizers of National Opt Out Day, the Wednesday before Thanksgiving when air travelers were urged to opt out of the full-body scanners at security checkpoints and instead submit to full-body patdowns—were outfoxed by the TSA. The government pre-empted the protest by turning off the machines in most airports during the Thanksgiving weekend. Everyone went through the metal detectors, just as before.

Now that Thanksgiving is over, the machines are back on and the "enhanced" pat-downs have resumed. I suspect that more people would prefer to have naked images of themselves seen by TSA agents in another room, than have themselves intimately touched by a TSA agent right in front of them.

But now, the TSA is in a bind. Regardless of whatever lobbying came before, or whatever former DHS officials had a financial interest in these scanners, the TSA has spent billions on those scanners, claiming they’re essential. But because people can opt out, the alternate manual method must be equally effective; otherwise, the terrorists could just opt out. If they make the pat-downs less invasive, it would be the same as admitting the scanners aren’t essential. Senior officials would get fired over that.

So not counting inconsequential modifications to demonstrate they’re "listening," the pat-downs will continue. And they’ll continue for everyone: children, abuse survivors, rape survivors, urostomy bag wearers, people in wheelchairs. It has to be that way; otherwise, the terrorists could simply adapt. They’d hide their explosives on their children or in their urostomy bags. They’d recruit rape survivors, abuse survivors, or seniors. They’d dress as pilots. They’d sneak their PETN through airport security using the very type of person who isn’t being screened.

And PETN is what the TSA is looking for these days. That’s pentaerythritol tetranitrate, the plastic explosive that both the Shoe Bomber and the Underwear Bomber attempted but failed to detonate. It’s what was mailed from Yemen. It’s in Iraq and Afghanistan. Guns and traditional bombs are passé; PETN is the terrorist tool of the future.

The problem is that no scanners or puffers can detect PETN; only swabs and dogs work. What the TSA hopes is that they will detect the bulge if someone is hiding a wad of it on their person. But they won’t catch PETN hidden in a body cavity. That doesn’t have to be as gross as you’re imagining; you can hide PETN in your mouth. A terrorist can go through the scanners a dozen times with bits in his mouth each time, and assemble a bigger bomb on the other side. Or he can roll it thin enough to be part of a garment, and sneak it through that way. These tricks aren’t new. In the days after the Underwear Bomber was stopped, a scanner manufacturer admitted that the machines might not have caught him.

So what’s next? Strip searches? Body cavity searches? TSA Administrator John Pistole said there would be no body cavity searches for now, but his reasons make no sense. He said that the case widely reported as being a body cavity bomb might not actually have been. While that appears to be true, what does that have to do with future bombs? He also said that even body cavity bombs would need "external initiators" that the TSA would be able to detect.

Do you think for a minute that the TSA can detect these "external initiators"? Do you think that if a terrorist took a laptop—or better yet, a less-common piece of electronics gear—and removed the insides and replaced them with a timer, a pressure sensor, a simple contact switch, or a radio frequency switch, the TSA guy behind the X-ray machine monitor would detect it? How about if those components were distributed over a few trips through airport security. On the other hand, if we believe the TSA can magically detect these "external initiators" so effectively that they make body-cavity searches unnecessary, why do we need the full-body scanners?

Either PETN is a danger that must be searched for, or it isn’t. Pistole was being either ignorant or evasive.

Once again, the TSA is covering their own asses by implementing security-theater measures to prevent the previous attack while ignoring any threats of future attacks. It’s the same thinking that caused them to ban box cutters after 9/11, screen shoes after Richard Reid, limit liquids after that London gang, and—I kid you not—ban printer cartridges over 16 ounces after they were used to house package bombs from Yemen. They act like the terrorists are incapable of thinking creatively, while the terrorists repeatedly demonstrate that can always come up with a new approach that circumvents the old measures.

On the plus side, PETN is very hard to get to explode. The pre-9/11 screening procedures, looking for obvious guns and bombs, forced the terrorists to build inefficient fusing mechanisms. We saw this when Abdulmutallab, the Underwear Bomber, used bottles of liquid and a syringe and 20 minutes in the bathroom to assemble his device, then set his pants on fire—and still failed to ignite his PETN-filled underwear. And when he failed, the passengers quickly subdued him.

The truth is that exactly two things have made air travel safer since 9/11: reinforcing cockpit doors and convincing passengers they need to fight back. The TSA should continue to screen checked luggage. They should start screening airport workers. And then they should return airport security to pre-9/11 levels and let the rest of their budget be used for better purposes. Investigation and intelligence is how we’re going to prevent terrorism, on airplanes and elsewhere. It’s how we caught the liquid bombers. It’s how we found the Yemeni printer-cartridge bombs. And it’s our best chance at stopping the next serious plot.

Because if a group of well-planned and well-funded terrorist plotters makes it to the airport, the chance is pretty low that those blue-shirted crotch-groping water-bottle-confiscating TSA agents are going to catch them. The agents are trying to do a good job, but the deck is so stacked against them that their job is impossible. Airport security is the last line of defense, and it’s not a very good one.

We have a job here, too, and it’s to be indomitable in the face of terrorism. The goal of terrorism is to terrorize us: to make us afraid, and make our government do exactly what the TSA is doing. When we react out of fear, the terrorists succeed even when their plots fail. But if we carry on as before, the terrorists fail—even when their plots succeed.

Close the Washington Monument

Securing the Washington Monument from terrorism has turned out to be a surprisingly difficult job. The concrete fence around the building protects it from attacking vehicles, but there’s no visually appealing way to house the airport-level security mechanisms the National Park Service has decided are a must for visitors. It is considering several options, but I think we should close the monument entirely. Let it stand, empty and inaccessible, as a monument to our fears.

An empty Washington Monument would serve as a constant reminder to those on Capitol Hill that they are afraid of the terrorists and what they could do. They’re afraid that by speaking honestly about the impossibility of attaining absolute security or the inevitability of terrorism—or that some American ideals are worth maintaining even in the face of adversity—they will be branded as “soft on terror.” And they’re afraid that Americans would vote them out of office if another attack occurred. Perhaps they’re right, but what has happened to leaders who aren’t afraid? What has happened to “the only thing we have to fear is fear itself”?

An empty Washington Monument would symbolize our lawmakers’ inability to take that kind of stand—and their inability to truly lead.

Some of them call terrorism an “existential threat” against our nation. It’s not. Even the events of 9/11, as horrific as they were, didn’t make an existential dent in our nation. Automobile-related fatalities—at 42,000 per year, more deaths each month, on average, than 9/11—aren’t, either. It’s our reaction to terrorism that threatens our nation, not terrorism itself. The empty monument would symbolize the empty rhetoric of those leaders who preach fear and then use that fear for their own political ends.

The day after Umar Farouk Abdulmutallab failed to blow up a Northwest jet with a bomb hidden in his underwear, Homeland Security Secretary Janet Napolitano said “The system worked.” I agreed. Plane lands safely, terrorist in custody, nobody injured except the terrorist. Seems like a working system to me. The empty monument would represent the politicians and press who pilloried her for her comment, and Napolitano herself, for backing down.

The empty monument would symbolize our war on the unexpected,—our overreaction to anything different or unusual—our harassment of photographers, and our probing of airline passengers. It would symbolize our “show me your papers” society, rife with ID checks and security cameras. As long as we’re willing to sacrifice essential liberties for a little temporary safety, we should keep the Washington Monument empty.

Terrorism isn’t a crime against people or property. It’s a crime against our minds, using the death of innocents and destruction of property to make us fearful. Terrorists use the media to magnify their actions and further spread fear. And when we react out of fear, when we change our policy to make our country less open, the terrorists succeed—even if their attacks fail. But when we refuse to be terrorized, when we’re indomitable in the face of terror, the terrorists fail—even if their attacks succeed.

We can reopen the monument when every foiled or failed terrorist plot causes us to praise our security, instead of redoubling it. When the occasional terrorist attack succeeds, as it inevitably will, we accept it, as we accept the murder rate and automobile-related death rate; and redouble our efforts to remain a free and open society.

The grand reopening of the Washington Monument will not occur when we’ve won the war on terror, because that will never happen. It won’t even occur when we’ve defeated al Qaeda. Militant Islamic terrorism has fractured into small, elusive groups. We can reopen the Washington Monument when we’ve defeated our fears, when we’ve come to accept that placing safety above all other virtues cedes too much power to government and that liberty is worth the risks, and that the price of freedom is accepting the possibility of crime.

I would proudly climb to the top of a monument to those ideals.

A version of this essay—there were a lot of changes and edits—originally appeared in the New York Daily News.

I wish I’d come up with the idea of closing the Washington Monument, but I didn’t. It was the Washington Post’s Philip Kennicott’s idea, although he didn’t say it with as much fervor.

Zoo Security

From a study on zoo security:

Among other measures, the scientists recommend not allowing animals to walk freely within the zoo grounds, and ensuring there is a physical barrier marking the zoo boundaries, and preventing individuals from escaping through drains, sewers or any other channels.

Isn’t all that sort of obvious?

New ATM Skimming Attack

In Europe, although the article doesn’t say where:

Many banks have fitted ATMs with devices that are designed to thwart criminals from attaching skimmers to the machines. But it now appears in some areas that those devices are being successfully removed and then modified for skimming, according to the latest report from the European ATM Security Team (EAST), which collects data on ATM fraud throughout Europe.

TSA Backscatter X-ray Backlash

Things are happening so fast that I don’t know if I should bother. But here are some links and observations.

The head of the Allied Pilots Association is telling its members to avoid both the full body scanners and the patdowns.

This first-hand report, from a man who refused to fly rather than subject himself to a full-body scan or an enhanced patdown, has been making the rounds. (The TSA is now investigating him.) It reminds me of Penn Jillette’s story from 2002.

A woman has a horrific story of opting-out of the full body scanners. More stories: this one about the TSA patting down a screaming toddler. And here’s Dave Barry’s encounter (also this NPR interview).

Sadly, I agree with this:

It is no accident that women have been complaining about being pulled out of line because of their big breasts, having their bodies commented on by TSA officials, and getting inappropriate touching when selected for pat-downs for nearly 10 years now, but just this week it went viral. It is no accident that CAIR identified Islamic head scarves (hijab) as an automatic trigger for extra screenings in January, but just this week it went viral. What was different?

Suddenly an able-bodied white man is the one who was complaining.

Seems that once you enter airport security, you need to be subjected to it—whether you decide to fly or not.

I experienced the enhanced patdown myself, at DCA, on Tuesday. It was invasive, but not as bad as these stories. It seems clear that TSA agents are inconsistent about these procedures. They’ve probably all had the same training, but individual agents put it into practice very differently.

Of course, airport security is an extra-Constitutional area, so there’s no clear redress mechanism for those subjected to too-intimate patdowns.

This video provides tips to parents flying with young children. Around 2:50 in, the reporter indicates that you can find out if your child has been pre-selected for secondary, and then recommends requesting “de-selection.” That doesn’t make sense.

Neither does this story, which says that the TSA will only touch Muslim women in the head and neck area.

Nor this story. The author convinces people on line to opt-out with him. After the first four opt-outs, the TSA just sent people through the metal detectors.

Yesterday, the TSA administrator John Pistole was grilled by the Senate Commerce, Science, and Transportation Committee on full-body scanners. Rep. Ron Paul introduced a bill to ban them. (His floor speech is here.) I’m one of the plaintiffs in a lawsuit to ban them.

Book for kids: My First Cavity Search. Cover seen at at TSA checkpoint.

T-shirts: one, two, and three and four. “Comply with Me” song parody. Political cartoons: one, two, three, and four. New TSA logo. Best TSA tweets, including “It’s not a grope. It’s a freedom pat.”

Good essay from a libertarian perspective. Two more. Marc Rotenberg’s essay. Ralph Nader’s essay. And the Los Angeles Times really screws up with this editorial: “Shut Up and Be Scanned.” Amitai Etzioni makes a better case for the machines.

Michael Chertoff, former Department of Homeland Security secretary, has been touting the full-body scanners, while at the same time maintaining a financial interest in the company that makes them.

There’s talk about the health risks of the machines, but I can’t believe you won’t get more radiation on the flight. Here’s some data:

A typical dental X-ray exposes the patient to about 2 millirems of radiation. According to one widely cited estimate, exposing each of 10,000 people to one rem (that is, 1,000 millirems) of radiation will likely lead to 8 excess cancer deaths. Using our assumption of linearity, that means that exposure to the 2 millirems of a typical dental X-ray would lead an individual to have an increased risk of dying from cancer of 16 hundred-thousandths of one percent. Given that very small risk, it is easy to see why most rational people would choose to undergo dental X-rays every few years to protect their teeth.

More importantly for our purposes, assuming that the radiation in a backscatter X-ray is about a hundredth the dose of a dental X-ray, we find that a backscatter X-ray increases the odds of dying from cancer by about 16 ten millionths of one percent. That suggests that for every billion passengers screened with backscatter radiation, about 16 will die from cancer as a result.

Given that there will be 600 million airplane passengers per year, that makes the machines deadlier than the terrorists.

Nate Silver on the hidden cost of these new airport security measures.

According to the Cornell study, roughly 130 inconvenienced travelers died every three months as a result of additional traffic fatalities brought on by substituting ground transit for air transit. That’s the equivalent of four fully-loaded Boeing 737s crashing each year.

Jeffrey Goldberg asked me which I would rather see for children: backscatter X-ray or enhanced pat down. After remarking what an icky choice it was, I opted for the X-ray; it’s less traumatic.

Here are a bunch of leaked body scans. They’re not from airports, but they should make you think twice before accepting the TSA’s assurances that the images will never be saved. RateMyBackscatter.com.

November 24 is National Opt Out Day. Doing this just before the Thanksgiving holiday is sure to clog up airports. Jeffrey Goldberg suggests that men wear kilts, commando style if possible.

At least one airport is opting out of the TSA entirely. I hadn’t known you could do that.

The New York Times on the protests.

Common sense from the Netherlands:

The security boss of Amsterdam’s Schiphol Airport is calling for an end to endless investment in new technology to improve airline security.

Marijn Ornstein said: “If you look at all the recent terrorist incidents, the bombs were detected because of human intelligence not because of screening … If even a fraction of what is spent on screening was invested in the intelligence services we would take a real step toward making air travel safer and more pleasant.”

And here’s Rafi Sela, former chief security officer of the Israel Airport Authority:

A leading Israeli airport security expert says the Canadian government has wasted millions of dollars to install “useless” imaging machines at airports across the country.

“I don’t know why everybody is running to buy these expensive and useless machines. I can overcome the body scanners with enough explosives to bring down a Boeing 747,” Rafi Sela told parliamentarians probing the state of aviation safety in Canada.

“That’s why we haven’t put them in our airport,” Sela said, referring to Tel Aviv’s Ben Gurion International Airport, which has some of the toughest security in the world.

They can be fooled by creased clothing. And remember this German video?

I’m quoted in the Los Angeles Times:

Some experts argue the new procedures could make passengers uncomfortable without providing a substantial increase in security. “Security measures that just force the bad guys to change tactics and targets are a waste of money,” said Bruce Schneier, a security expert who works for British Telecom. “It would be better to put that money into investigations and intelligence.”

I’m quoted in The Wall Street Journal twice—once as saying:

“All these machines require you to guess the plot correctly. If you don’t, then they are completely worthless,” said Bruce Schneier, a security expert.

Mr. Schneier and some other experts argue that assembling better intelligence on fliers is the key to making travel safer.

and once as saying:

Security guru Bruce Schneier, a plaintiff in the scanner suit, calls this “magical thinking . . . Descend on what the terrorists happened to do last time, and we’ll all be safe. As if they won’t think of something else.”

In 2005, I wrote:

I’m not impressed with this security trade-off. Yes, backscatter X-ray machines might be able to detect things that conventional screening might miss. But I already think we’re spending too much effort screening airplane passengers at the expense of screening luggage and airport employees…to say nothing of the money we should be spending on non-airport security.

On the other side, these machines are expensive and the technology is incredibly intrusive. I don’t think that people should be subjected to strip searches before they board airplanes. And I believe that most people would be appalled by the prospect of security screeners seeing them naked.

I believe that there will be a groundswell of popular opposition to this idea. Aside from the usual list of pro-privacy and pro-liberty groups, I expect fundamentalist Christian groups to be appalled by this technology. I think we can get a bevy of supermodels to speak out against the invasiveness of the search.

On the other hand, CBS News is reporting that 81% of Americans support full-body scans. Maybe they should only ask flying Americans.

I still stand by this, also from 2005:

Exactly two things have made airline travel safer since 9/11: reinforcement of cockpit doors, and passengers who now know that they may have to fight back. Everything else—Secure Flight and Trusted Traveler included—is security theater. We would all be a lot safer if, instead, we implemented enhanced baggage security—both ensuring that a passenger’s bags don’t fly unless he does, and explosives screening for all baggage—as well as background checks and increased screening for airport employees.

Then we could take all the money we save and apply it to intelligence, investigation and emergency response. These are security measures that pay dividends regardless of what the terrorists are planning next, whether it’s the movie plot threat of the moment, or something entirely different.

And this, written in 2010 after the Underwear Bomber failed:

Finally, we need to be indomitable. The real security failure on Christmas Day was in our reaction. We’re reacting out of fear, wasting money on the story rather than securing ourselves against the threat. Abdulmutallab succeeded in causing terror even though his attack failed.

If we refuse to be terrorized, if we refuse to implement security theater and remember that we can never completely eliminate the risk of terrorism, then the terrorists fail even if their attacks succeed.

See these two essays of mine as well, from the same time.

EDITED TO ADD: (11/19): Lots more political cartoons.

Good summary of your legal rights and options from the ACLU. They also have a form you can fill out and send to your Congresscritter.

This has to win for DHS Quote of the Year, from Secretary Janet Napolitano on the issue:

I really want to say, look, let’s be realistic and use our common sense.

The TSA doesn’t train its screeners very well. A response to a letter-writer from Sen. Coburn. From Slate: "Does the TSA Ever Catch Terrorists?" A pilot’s story. The screeners’ point of view. Good essay from the National Post.

Fun with the Playmobil airline security screening playset.

Meg McLain, whose horrific story I linked to above, lied. Here’s an interview with her.

EDITED TO ADD (11/20): I was interviewed by Popular Mechanics.

Woman forced to remove prosthetic breast. TSO officer caught saying “heads up, got a cutie for you” into his headset to the other officers. Complication news video of TSA behavior.

Here’s an alert you can hand out to passengers at security checkpoints where there are backscatter machines.

EDITED TO ADD (11/21): Me in an Associated Press piece on the anti-TSA backlash:

“After 9/11 people were scared and when people are scared they’ll do anything for someone who will make them less scared,” said Bruce Schneier, a Minneapolis security technology expert who has long been critical of the TSA. “But … this is particularly invasive. It’s strip-searching. It’s body groping. As abhorrent goes, this pegs it.”

President Obama comments:

“I understand people’s frustrations, and what I’ve said to the TSA is that you have to constantly refine and measure whether what we’re doing is the only way to assure the American people’s safety. And you also have to think through are there other ways of doing it that are less intrusive,” Obama said.

“But at this point, TSA in consultation with counterterrorism experts have indicated to me that the procedures that they have been putting in place are the only ones right now that they consider to be effective against the kind of threat that we saw in the Christmas Day bombing.”

TSA sendup on Saturday Night Live yesterday.

EDITED TO ADD (11/22): The thing about Muslim women being exempt seems to be based on a misreading of this press release. What they seem to be saying is that if you’re selected because you could have something under your hijab, then they only need to just pat down the area the hijab covers. It’s not a special exemption.

TSA Administrator John Pistole comments:

We are constantly evaluating and adapting our security measures, and as we have said from the beginning, we are seeking to strike the right balance between privacy and security. In all such security programs, especially those that are applied nation-wide, there is a continual process of refinement and adjustment to ensure that best practices are applied and that feedback and comment from the traveling public is taken into account.

EDITED TO ADD (11/23): Fantastic infographic. Excellent poster image. This, too. And another political cartoon.

Yesterday I participated in a New York Times “Room for Debate” discussion on airline security. My contribution is nothing I haven’t said before, so I won’t reprint it here. The other participants are worth reading too.

More from Nate Silver, on public opinion and the likely TSA reaction:

It is perhaps foolish to predict how the T.S.A. will respond this time—when they have relaxed rules in the past, they have done so quietly, rather than in response to some acute public backlash. But caution aside, I would be surprised if the new procedures survived much past the New Year without significant modification.

CNN’s advice to the public.

Things are definitely strained out there:

Through a statement released by his attorney Sunday night, Wolanyk said “TSA needs to see that I’m not carrying any weapons, explosives, or other prohibited substances, I refuse to have images of my naked body viewed by perfect strangers, and having been felt up for the first time by TSA the week prior (I travel frequently) I was not willing to be molested again.”

Wolanyk’s attorney said that TSA requested his client put his clothes on so he could be patted down properly but his client refused to put his clothes back on. He never refused a pat down, according to his attorney. Wolanyk was arrested for refusing to complete the security process.

From the same article:

A woman, identified by Harbor police as Danielle Kelli Hayman,39, of San Diego was detained for recording the incident on a phone.

That’s much more worrying.

Interview with Brian Michael Jenkins, a senior advisor at the RAND Corp. and a former member of the White House Commission on Aviation Safety and Security.

Here’s someone who managed to avoid both the full-body scanners and the enhanced pat down. It took him two and a half hours. And here someone who got patted down, and managed to sneak two razor blades through security anyway.

How the TSA will deal with people with disabilities. How the pat downs affect survivors of sexual assault. (Read also the comments here.) Juan Cole on how airport security has shifted from looking for people with guns and traditional bombs to looking for people with PETN. And TSA-proof underwear.

EDITED TO ADD (11/24): Information on the health risks of the backscatter machines. And here’s a woman who stripped down to her underwear before going through airport security. This comes from a perspective I generally don’t buy, but it’s hard to dismiss his writing. I don’t think it’s a conspiracy, but I do think it’s a trend. “This Modern World” has a comic on the topic. Slate on the lack of guidelines. Why the TSA should be privatized.

EDITED TO ADD (11/25): I was on Keith Olbermann last night.

Securing the Washington Monument

Good article on security options for the Washington Monument:

Unfortunately, the bureaucratic gears are already grinding, and what will be presented to the public Monday doesn’t include important options, including what became known as the “tunnel” in previous discussions of the issue. Nor does it include the choice of more minimal visitor screening—simple wanding or visual bag inspection—that might not require costly and intrusive changes to the structure. The choice to accept risk isn’t on the table, either. Finally, and although it might seem paradoxical given how important resisting security authoritarianism is to preserving the symbolism of freedom, it doesn’t take seriously the idea that perhaps the monument’s interior should be closed altogether—a small concession that might have collateral benefits.

[…]

Closing the interior of the monument, the construction of which was suspended during the Civil War, would remind the public of the effect that fears engendered by the current war on terrorism have had on public space. Closing it as a symbolic act might initiate an overdue discussion about the loss of even more important public spaces, including the front entrance of the Supreme Court and the west terrace of the Capitol. It would be a dramatic reminder of the choices we as a nation have made, and perhaps an inspiration to change our ways in favor of a more open, risk-tolerant society that understands public space always has some element of danger.

EDITED TO ADD (11/15): More information on the decision process.

Crowdsourcing Surveillance

Internet Eyes is a U.K. startup designed to crowdsource digital surveillance. People pay a small fee to become a “Viewer.” Once they do, they can log onto the site and view live anonymous feeds from surveillance cameras at retail stores. If they notice someone shoplifting, they can alert the store owner. Viewers get rated on their ability to differentiate real shoplifting from false alarms, can win 1000 pounds if they detect the most shoplifting in some time interval, and otherwise get paid a wage that most likely won’t cover their initial fee.

Although the system has some nod towards privacy, groups like Privacy International oppose the system for fostering a culture of citizen spies. More fundamentally, though, I don’t think the system will work. Internet Eyes is primarily relying on voyeurism to compensate its Viewers. But most of what goes on in a retail store is incredibly boring. Some of it is actually voyeuristic, and very little of it is criminal. The incentives just aren’t there for Viewers to do more than peek, and there’s no obvious way to discouraging them from siding with the shoplifter and just watch the scenario unfold.

This isn’t the first time groups have tried to crowdsource surveillance camera monitoring. Texas’s Virtual Border Patrol tried the same thing: deputizing the general public to monitor the Texas-Mexico border. It ran out of money last year, and was widely criticized as a joke.

This system suffered the same problems as Internet Eyes—not enough incentive to do a good job, boredom because crime is the rare exception—as well as the fact that false alarms were very expensive to deal with.

Both of these systems remind me of the one time this idea was conceptualized correctly. Invented in 2003 by my friend and colleague Jay Walker, US HomeGuard also tried to crowdsource surveillance camera monitoring. But this system focused on one very specific security concern: people in no-mans areas. These are areas between fences at nuclear power plants or oil refineries, border zones, areas around dams and reservoirs, and so on: areas where there should never be anyone.

The idea is that people would register to become “spotters.” They would get paid a decent wage (that and patriotism was the incentive), receive a stream of still photos, and be asked a very simple question: “Is there a person or a vehicle in this picture?” If a spotter clicked “yes,” the photo—and the camera—would be referred to whatever professional response the camera owner had set up.

HomeGuard would monitor the monitors in two ways. One, by sending stored, known, photos to people regularly to verify that they were paying attention. And two, by sending live photos to multiple spotters and correlating the results, to many more monitors if a spotter claimed to have spotted a person or vehicle.

Just knowing that there’s a person or a vehicle in a no-mans area is only the first step in a useful response, and HomeGuard envisioned a bunch of enhancements to the rest of that system. Flagged photos could be sent to the digital phones of patrolling guards, cameras could be controlled remotely by those guards, and speakers in the cameras could issue warnings. Remote citizen spotters were only useful for that first step, looking for a person or a vehicle in a photo that shouldn’t contain any. Only real guards at the site itself could tell an intruder from the occasional maintenance person.

Of course the system isn’t perfect. A would-be infiltrator could sneak past the spotters by holding a bush in front of him, or disguising himself as a vending machine. But it does fill in a gap in what fully automated systems can do, at least until image processing and artificial intelligence get significantly better.

HomeGuard never got off the ground. There was never any good data about whether spotters were more effective than motion sensors as a first level of defense. But more importantly, Walker says that the politics surrounding homeland security money post-9/11 was just too great to penetrate, and that as an outsider he couldn’t get his ideas heard. Today, probably, the patriotic fervor that gripped so many people post-9/11 has dampened, and he’d probably have to pay his spotters more than he envisioned seven years ago. Still, I thought it was a clever idea then and I still think it’s a clever idea—and it’s an example of how to do surveillance crowdsourcing correctly.

Making the system more general runs into all sorts of problems. An amateur can spot a person or vehicle pretty easily, but is much harder pressed to notice a shoplifter. The privacy implications of showing random people pictures of no-mans lands is minimal, while a busy store is another matter—stores have enough individuality to be identifiable, as do people. Public photo tagging will even allow the process to be automated. And, of course, the normalization of a spy-on-your-neighbor surveillance society where it’s perfectly reasonable to watch each other on cameras just in case one of us does something wrong.
