Security Implications of "Lower-Risk Aircraft"

Interesting paper: Paul J. Freitas (2012), “Passenger aviation security, risk management, and simple physics,” Journal of Transportation Security.

Abstract: Since the September 11, 2001 suicide hijacking attacks on the United States, preventing similar attacks from recurring has been perhaps the most important goal of aviation security. In addition to other measures, the US government has increased passenger screening requirements to unprecedented levels. This has raised a number of concerns regarding passenger safety from radiation risks associated with airport body scanners, psychological trauma associated with pat-down searches, and general cost/benefit analysis concerns regarding security measures. Screening changes, however, may not be the best way to address the safety and security issues exposed by the September 11 attacks. Here we use simple physics concepts (kinetic energy and chemical potential energy) to evaluate the relative risks from crash damage for various aircraft types. A worst-case jumbo jet crash can result in an energy release comparable to that of a small nuclear weapon, but other aircraft types are considerably less dangerous. Understanding these risks suggests that aircraft with lower fuel capacities, speeds, and weights pose substantially reduced risk over other aircraft types. Lower-risk aircraft may not warrant invasive screening as they pose less risk than other risks commonly accepted in American society, like tanker truck accidents. Allowing passengers to avoid invasive screening for lower-risk aircraft would introduce competition into passenger aviation that might lead to better overall improvements in security and general safety than passenger screening alone is capable of achieving.

The full paper is behind a paywall, but here is a preprint.

Possibly the Most Incompetent TSA Story Yet

The storyline:

  1. TSA screener finds two pipes in passenger’s bags.
  2. Screener determines that they’re not a threat.
  3. Screener confiscates them anyway, because of their “material and appearance.”
  4. Because they’re not actually a threat, screener leaves them at the checkpoint.
  5. Everyone forgets about them.
  6. Six hours later, the next shift of TSA screeners notices the pipes and—not being able to explain how they got there and, presumably, because of their “material and appearance”—calls the police bomb squad to remove the pipes.
  7. TSA does not evacuate the airport, or even close the checkpoint, because—well, we don’t know why.

I don’t even know where to begin.

British Tourists Arrested in the U.S. for Tweeting

Does this story make sense to anyone?

The Department of Homeland Security flagged him as a potential threat when he posted an excited tweet to his pals about his forthcoming trip to Hollywood which read: ‘Free this week, for quick gossip/prep before I go and destroy America’.

After making their way through passport control at Los Angeles International Airport (LAX) last Monday afternoon the pair were detained by armed guards.

Despite telling officials the term ‘destroy’ was British slang for ‘party’, they were held on suspicion of planning to ‘commit crimes’ and had their passports confiscated.

There just as to be more than this story. The DHS isn’t monitoring the Tweets of random British tourists—they just can’t be.

EDITED TO ADD (1/30): According to DHS documents received by EPIC, the DHS monitors the Internet, including social media.

In February 2011, the Department of Homeland Security announced that the agency planned to implement a program that would monitor media content, including social media data. The proposed initiatives would gather information from “online forums, blogs, public websites, and messages boards” and disseminate information to “federal, state, local, and foreign government and private sector partners.” The program would be executed, in part, by individuals who established fictitious usernames and passwords to create covert social media profiles to spy on other users. The agency stated it would store personal information for up to five years.

[…]

The records reveal that the DHS is paying General Dynamics to monitor the news. The agency instructed the company to monitor for “[media] reports that reflect adversely on the U.S. Government, DHS, or prevent, protect, respond government activities.”

[…]

The DHS instructed the company to “Monitor public social communications on the Internet.” The records list the websites that will be monitored, including the comments sections of [The New York Times, The Los Angeles Times, the Huffington Post, the Drudge Report, Wired, and ABC News.]”

Still, I have trouble believing that this is what happened. For this to work General Dynamics would have had to monitor Twitter for key words. (“Destroy America” is certainly a good key word to search for.) Then, they would have to find out the real name associated with the Twitter account—unlike Facebook or Google+, Twitter doesn’t have real name information—so the TSA could cross-index that name with the airline’s passenger manifests. Then the TSA has to get all this information into the INS computers, so that the border control agent knows to detain him. Sure, it sounds straightforward, but getting all those computers to talk to each other that fast isn’t easy. There has to be more going on here.

EDITED TO ADD (1/30): One reader points out that this story is from the Daily Mail, and that it’s prudent to wait for some more reputable news source to report the story.

EDITED TO ADD (1/30): There’s another story from The Register, but they’re just using the Daily Mail.

EDITED TO ADD (1/30): The FBI is looking for someone to build them a system that can monitor social networks.

The information comes from a document released on 19 January looking for companies who might want to build a monitoring system for the FBI. It spells out what the bureau wants from such a system and invites potential contractors to reply by 10 February.

The bureau’s wish list calls for the system to be able to automatically search “publicly available” material from Facebook, Twitter and other social media sites for keywords relating to terrorism, surveillance operations, online crime and other FBI missions. Agents would be alerted if the searches produce evidence of “breaking events, incidents, and emerging threats.”

Agents will have the option of displaying the tweets and other material captured by the system on a map, to which they can add layers of other data, including the locations of US embassies and military installations, details of previous terrorist attacks and the output from local traffic cameras.

EDITED TO ADD (1/30): New reports are saying that customs was tipped off about the two people, and their detention was not a result of data mining:

“Based on information provided by the LAX Port Authority Infoline—a suspicious activity tipline—CBP conducted a secondary interview of two subjects presenting for entry into the United States,” says the spokesperson, who notes that the CBP “denies entry to thousands of individuals” each year. “Information gathered during this interview revealed that both individuals were inadmissible to the United States and were returned to their country of residence.”

This makes a lot more sense to me.

Abolish the Department of Homeland Security

I have a love/hate relationship with the Cato Institute. Most of their analysis I strongly disagree with, but some of it I equally strongly agree with. Last September 11—the tenth anniversary of 9/11—Cato’s David Rittgers published “Abolish the Department of Homeland Security“:

DHS has too many subdivisions in too many disparate fields to operate effectively. Agencies with responsibilities for counterfeiting investigations, border security, disaster preparedness, federal law enforcement training, biological warfare defense, and computer incident response find themselves under the same cabinet official. This arrangement has not enhanced the government’s competence. Americans are not safer because the head of DHS is simultaneously responsible for airport security and governmental efforts to counter potential flu epidemics.

National defense is a key governmental responsibility, but focusing too many resources on trying to defend every potential terrorist target is a recipe for wasteful spending. Our limited resources are better spent on investigating and arresting aspiring terrorists. DHS responsibilities for aviation security, domestic surveillance, and port security have made it too easy for politicians to disguise pork barrel spending in red, white, and blue. Politicians want to bring money home to their districts, and as a result, DHS appropriations too often differ from what ought to be DHS priorities.

I agree with that. In fact, in 2003, when the country was debating a single organization that would be responsible for most (not all, since the Justice Department, the State Department, and the Department of Defense were too powerful to lose any pieces of themselves) of the country’s counterterrorism efforts, I wrote:

Our nation may actually be less secure if the Department of Homeland Security eventually takes over the responsibilities of existing agencies. The last thing we want is for the Department of Energy, the Department of Commerce, and the Department of State to say: “Security; that’s the responsibility of the DHS.”

Security is the responsibility of everyone in government. We won’t defeat terrorism by finding a single thing that works all the time. We’ll defeat terrorism when every little thing works in its own way, and together provides an immune system for our society. Unless the DHS distributes security responsibility even as it centralizes coordination, it won’t improve our nation’s security.

Back to the Cato report:

The Department of Homeland Security should be abolished and its components reorganized into more practical groupings. The agencies tasked with immigration, border security, and customs enforcement belong under the same oversight agency, which could appropriately be called the Border Security Administration. The Transportation Security Administration and Federal Air Marshals Service should be abolished, and the federal government should end support for fusion centers. The remaining DHS organizations should return to their former parent agencies.

Hard to argue with most of that, although abolishing the TSA isn’t a good idea. Airport security should be rolled back to pre-9/11 levels, but someone is going to have to be in charge of it. Putting the airlines in charge of it doesn’t make sense; their incentives are going to be passenger service rather than security. Some government agency either has to hire the screeners and staff the checkpoints, or make and enforce rules for contractor-staffed checkpoints to follow.

Last November, the U.S. Congressional Republicans published a report very critical of the TSA: “A Decade Later: A Call for TSA Reform.”

This report is an examination and critical analysis of the development, evolution, and current status and performance of TSA ten years after its creation. Since its inception, TSA has lost its focus on transportation security. Instead, it has grown into an enormous, inflexible and distracted bureaucracy, more concerned with human resource management and consolidating power, and acting reactively instead of proactively. As discussed more fully in the Recommendations section on page 18, TSA must realign its responsibilities as a federal regulator and focus on analyzing intelligence, setting screening and security standards based on risk, auditing passenger and baggage screening operations, and ensuring compliance with national screening standards.

In a related link, there’s a response to a petition to abolish the TSA. The response is by TSA administrator John Pistole, so it’s not the most objective piece of writing on the topic, and doesn’t actually respond to the petition:

Why TSA Exists.

TSA was created two months after the September 11 terrorist attacks, when Congress passed the Aviation and Transportation Security Act (ATSA) [.pdf] to keep the millions of Americans who travel each day safe and secure across numerous modes of transportation.

Over the past 10 years, TSA has strengthened security by creating successful programs and deploying technologies that were not in place prior to September 11, while also taking steps whenever possible to enhance the passenger experience. Here are just a few of the many steps TSA has taken to strengthen our multi-layered approach to security….

[…]

Our Nation is safer and better prepared today because of these and other efforts of the Department of Homeland Security, TSA, and our federal, state, local and international partners. TSA is constantly identifying ways to continue to strengthen security and improve the passenger experience and appreciates the feedback of the public.

Pistole just assumes that what his organization is doing is important, and never even mentions how much it costs or whether it’s worth it.

The TSA Proves its Own Irrelevance

Have you wondered what $1.2 billion in airport security gets you? The TSA has compiled its own “Top 10 Good Catches of 2011“:

10) Snakes, turtles, and birds were found at Miami (MIA) and Los Angeles (LAX). I’m just happy there weren’t any lions, tigers, and bears…

[…]

3) Over 1,200 firearms were discovered at TSA checkpoints across the nation in 2011. Many guns are found loaded with rounds in the chamber. Most passengers simply state they forgot they had a gun in their bag.

2) A loaded .380 pistol was found strapped to passenger’s ankle with the body scanner at Detroit (DTW). You guessed it, he forgot it was there…

1) Small chunks of C4 explosives were found in passenger’s checked luggage in Yuma (YUM). Believe it or not, he was brining it home to show his family.

That’s right; not a single terrorist on the list. Mostly forgetful, and entirely innocent, people. Note that they fail to point out that the firearms and knives would have been just as easily caught by pre-9/11 screening procedures. And that the C4—their #1 “good catch”—was on the return flight; they missed it the first time. So only 1 for 2 on that one.

And the TSA decided not to mention its stupidest confiscations:

TSA confiscates a butter knife from an airline pilot. TSA confiscates a teenage girl’s purse with an embroidered handgun design. TSA confiscates a 4-inch plastic rifle from a GI Joe action doll on the grounds that it’s a “replica weapon.” TSA confiscates a liquid-filled baby rattle from airline pilot’s infant daughter. TSA confiscates a plastic “Star Wars” lightsaber from a toddler.

In related news, here’s a rebuttal of the the Vanity Fair article about the TSA and airline security that featured me. I agree with the two points at the end of the post; I just don’t think it changes any of my analysis.

Merry Christmas from the TSA

Cupcakes deemed security threat:

Rebecca Hains says she was going through security at the airport in Las Vegas when a TSA agent pulled her aside and said the cupcake frosting was “gel-like” enough to constitute a security risk.

The TSA has officially jumped the shark.

EDITED TO ADD (1/12): The TSA claims that the cupcake they confiscated was in a jar. So this is a less obviously stupid story than I previously thought.

EDITED TO ADD (1/13): The cupcake lady says that the TSA is lying.

Yet More Fear-Mongering from the DHS

Al Qaeda is sewing bombs into people. Actually, not really. This is an “aspirational” terrorist threat, which basically means that someone mentioned it while drunk in a bar somewhere. Of course, that won’t stop the DHS from trying to terrorize people with the idea and the security-industrial complex from selling us an expensive “solution” to reduce our fears.

Wired: “So: a disruptive, potentially expensive panic based on a wild aspirational scheme? Actually, that sounds a lot like al-Qaida. And the TSA.”

Me: “Refuse to be terrorized.”
