The Onion on TSA's Liquid Ban

Elaine Siegel, Sales Representative
“Thank God. I don’t think I’d be able to make one more flight from New York to Chicago with a mouthful of shampoo.”

Alex Hunter, Surveyor
“The ban was a necessary precaution. We have to be willing to make these kinds of sacrifices if we’re going to prevent scientifically impossible terrorist attacks.”

Ed Johansen, Systems Analyst
“By giving passengers renewed access to these gels, lotions, and shampoos, we run the risk of creating a very dangerous and highly evasive super-slippery terrorist able to avoid all manners of restraint.”

More Than 10 Ways to Avoid the Next 9/11

From yesterday’s New York Times, “Ten Ways to Avoid the Next 9/11”:

If we are fortunate, we will open our newspapers this morning knowing that there have been no major terrorist attacks on American soil in nearly five years. Did we just get lucky?

The Op-Ed page asked 10 people with experience in security and counterterrorism to answer the following question: What is one major reason the United States has not suffered a major attack since 2001, and what is the one thing you would recommend the nation do in order to avoid attacks in the future?

Actually, they asked more than 10, myself included. But some of us were cut because they didn’t have enough space. This was my essay:

Despite what you see in the movies and on television, it’s actually very difficult to execute a major terrorist act. It’s hard to organize, plan, and execute an attack, and it’s all too easy to slip up and get caught. Combine that with our intelligence work tracking terrorist cells and interdicting terrorist funding, and you have a climate where major attacks are rare. In many ways, the success of 9/11 was an anomaly; there were many points where it could have failed. The main reason we haven’t seen another 9/11 is that it isn’t as easy as it looks.

Much of our counterterrorist efforts are nothing more than security theater: ineffectual measures that look good. Forget the “war on terror”; the difficulty isn’t killing or arresting the terrorists, it’s finding them. Terrorism is a law enforcement problem, and needs to be treated as such. For example, none of our post-9/11 airline security measures would have stopped the London shampoo bombers. The lesson of London is that our best defense is intelligence and investigation. Rather than spending money on airline security, or sports stadium security—measures that require us to guess the plot correctly in order to be effective—we’re better off spending money on measures that are effective regardless of the plot.

Intelligence and investigation have kept us safe from terrorism in the past, and will continue to do so in the future. If the CIA and FBI had done a better job of coordinating and sharing data in 2001, 9/11 would have been another failed attempt. Coordination has gotten better, and those agencies are better funded—but it’s still not enough. Whenever you read about the billions being spent on national ID cards or massive data mining programs or new airport security measures, think about the number of intelligence agents that the same money could buy. That’s where we’re going to see the greatest return on our security investment.

Bomb or Not?

Can you identify the bombs?

In related news, here’s a guy who makes it through security with a live vibrator in his pants.

There’s also a funny video on Dutch TV. A screener scans a passenger’s bag, putting aside several obvious bags of cocaine to warn him about a very tiny nail file.

Here’s where to buy stuff seized at Boston’s Logan Airport. I also read somewhere that some stuff ends up on eBay.

And finally,Quinn Norton said: “I think someone should try to blow up a plane with a piece of ID, just to watch the TSA’s mind implode.”

Antiterrorism Expert Claims to Have Smuggled Bomb onto Airplane Twice

I don’t know how much of this to believe.

A man wearing a jacket and carrying a bag was able to sneak a bomb onto a flight from Manila to Davao City last month at the height of the nationwide security alert after Britain uncovered a plot to blow up transatlantic planes.

The man pulled off the same stunt on the return flight to Manila.

Had he detonated the bomb, he would have turned the commercial plane into a fireball and killed himself, the crew and hundreds of other passengers.

The man turned out to be a civilian antiterrorism expert tapped by a government official to test security measures at Philippine airports after British police foiled a plan to blow up US-bound planes in midair using liquid explosives.

In particular, if he actually built a working bomb in an airplane lavatory, he’s an idiot. Yes, C4 is stable, but playing with live electrical detonators near high-power radios is just stupid. On the other hand, bringing everything through security and onto the plane is perfectly plausible. Security is so focused on catching people with lipstick and shampoo that they’re ignoring actual threats.

Details on the British Terrorist Arrest

Details are emerging:

There was some serious cash flow from someone, presumably someone abroad.
There was no imminent threat.
However, the threat was real. And it seems pretty clear that it would have bypassed all existing airport security systems.
The conspirators were radicalized by the war in Iraq, although it is impossible to say whether they would have been otherwise radicalized without it.
They were caught through police work, not through any broad surveillance, and were under surveillance for more than a year.

What pisses me off most is the second item. By arresting the conspirators early, the police squandered the chance to learn more about the network and arrest more of them—and to present a less flimsy case. There have been many news reports detailing how the U.S. pressured the UK government to make the arrests sooner, possibly out of political motivations. (And then Scotland Yard got annoyed at the U.S. leaking plot details to the press, hampering their case.)

My initial comments on the arrest are here. I still think that all of the new airline security measures are an overreaction (This essay makes the same point, as well as describing a 1995 terrorist plot that was remarkably similar in both materials and modus operandi—and didn’t result in a complete ban on liquids.)

As I said on a radio interview a couple of weeks ago: “We ban guns and knives, and the terrorists use box cutters. We ban box cutters and corkscrews, and they hide explosives in their shoes. We screen shoes, and the terrorists use liquids. We ban liquids, and the terrorist will use something else. It’s not a fair game, because the terrorists get to see our security measures before they plan their attack.” And it’s not a game we can win. So let’s stop playing, and play a game we actually can win. The real lesson of the London arrests is that investigation and intelligence work.

What the Terrorists Want

On Aug. 16, two men were escorted off a plane headed for Manchester, England, because some passengers thought they looked either Asian or Middle Eastern, might have been talking Arabic, wore leather jackets, and looked at their watches—and the passengers refused to fly with them on board. The men were questioned for several hours and then released.

On Aug. 15, an entire airport terminal was evacuated because someone’s cosmetics triggered a false positive for explosives. The same day, a Muslim man was removed from an airplane in Denver for reciting prayers. The Transportation Security Administration decided that the flight crew overreacted, but he still had to spend the night in Denver before flying home the next day. The next day, a Port of Seattle terminal was evacuated because a couple of dogs gave a false alarm for explosives.

On Aug. 19, a plane made an emergency landing in Tampa, Florida, after the crew became suspicious because two of the lavatory doors were locked. The plane was searched, but nothing was found. Meanwhile, a man who tampered with a bathroom smoke detector on a flight to San Antonio was cleared of terrorism, but only after having his house searched.

On Aug. 16, a woman suffered a panic attack and became violent on a flight from London to Washington, so the plane was escorted to the Boston airport by fighter jets. “The woman was carrying hand cream and matches but was not a terrorist threat,” said the TSA spokesman after the incident.

And on Aug. 18, a plane flying from London to Egypt made an emergency landing in Italy when someone found a bomb threat scrawled on an air sickness bag. Nothing was found on the plane, and no one knows how long the note was on board.

I’d like everyone to take a deep breath and listen for a minute.

The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets; they are collateral damage. And blowing up planes, trains, markets or buses is not the goal; those are just tactics. The real targets of terrorism are the rest of us: the billions of us who are not killed but are terrorized because of the killing. The real point of terrorism is not the act itself, but our reaction to the act.

And we’re doing exactly what the terrorists want.

We’re all a little jumpy after the recent arrest of 23 terror suspects in Great Britain. The men were reportedly plotting a liquid-explosive attack on airplanes, and both the press and politicians have been trumpeting the story ever since.

In truth, it’s doubtful that their plan would have succeeded; chemists have been debunking the idea since it became public. Certainly the suspects were a long way off from trying: None had bought airline tickets, and some didn’t even have passports.

Regardless of the threat, from the would-be bombers’ perspective, the explosives and planes were merely tactics. Their goal was to cause terror, and in that they’ve succeeded.

Imagine for a moment what would have happened if they had blown up 10 planes. There would be canceled flights, chaos at airports, bans on carry-on luggage, world leaders talking tough new security measures, political posturing and all sorts of false alarms as jittery people panicked. To a lesser degree, that’s basically what’s happening right now.

Our politicians help the terrorists every time they use fear as a campaign tactic. The press helps every time it writes scare stories about the plot and the threat. And if we’re terrified, and we share that fear, we help. All of these actions intensify and repeat the terrorists’ actions, and increase the effects of their terror.

(I am not saying that the politicians and press are terrorists, or that they share any of the blame for terrorist attacks. I’m not that stupid. But the subject of terrorism is more complex than it appears, and understanding its various causes and effects are vital for understanding how to best deal with it.)

The implausible plots and false alarms actually hurt us in two ways. Not only do they increase the level of fear, but they also waste time and resources that could be better spent fighting the real threats and increasing actual security. I’ll bet the terrorists are laughing at us.

Another thought experiment: Imagine for a moment that the British government arrested the 23 suspects without fanfare. Imagine that the TSA and its European counterparts didn’t engage in pointless airline-security measures like banning liquids. And imagine that the press didn’t write about it endlessly, and that the politicians didn’t use the event to remind us all how scared we should be. If we’d reacted that way, then the terrorists would have truly failed.

It’s time we calm down and fight terror with antiterror. This does not mean that we simply roll over and accept terrorism. There are things our government can and should do to fight terrorism, most of them involving intelligence and investigation—and not focusing on specific plots.

But our job is to remain steadfast in the face of terror, to refuse to be terrorized. Our job is to not panic every time two Muslims stand together checking their watches. There are approximately 1 billion Muslims in the world, a large percentage of them not Arab, and about 320 million Arabs in the Middle East, the overwhelming majority of them not terrorists. Our job is to think critically and rationally, and to ignore the cacophony of other interests trying to use terrorism to advance political careers or increase a television show’s viewership.

The surest defense against terrorism is to refuse to be terrorized. Our job is to recognize that terrorism is just one of the risks we face, and not a particularly common one at that. And our job is to fight those politicians who use fear as an excuse to take away our liberties and promote security theater that wastes money and doesn’t make us any safer.

On the Implausibility of the Explosives Plot

Really interesting analysis of the chemistry involved in the alleged UK terrorist plot:

Based on the claims in the media, it sounds like the idea was to mix H₂O₂ (hydrogen peroxide, but not the low test kind you get at the pharmacy), H₂SO₄ (sulfuric acid, of necessity very concentrated for it to work at all), and acetone (known to people worldwide as nail polish remover), to make acetone peroxides. You first have to mix the H₂O₂ and H₂SO₄ to get a powerful oxidizer, and then you use it on acetone to get the peroxides, which are indeed explosive.

A mix of H₂O₂ and H₂SO₄, commonly called “piranha bath”, is used in orgo labs around the world for cleaning the last traces out of organic material out of glassware when you need it *really* clean—thus, many people who work around organic labs are familiar with it. When you mix it, it heats like mad, which is a common thing when you mix concentrated sulfuric acid with anything. It is very easy to end up with a spattering mess. You don’t want to be around the stuff in general. Here, have a look at a typical warning list from a lab about the stuff:

http://www.mne.umd.edu/LAMP/Sop/Piranha_SOP.htm

Now you may protest “but terrorists who are willing to commit suicide aren’t going to be deterred by being injured while mixing their precursor chemicals!”—but of course, determination isn’t the issue here, getting the thing done well enough to make the plane go boom is the issue. There is also the small matter of explaining to the guy next to you what you’re doing, or doing it in a tiny airplane bathroom while the plane jitters about.

Now, they could of course mix up their oxidizer in advance, but then finding a container to keep the stuff in that isn’t going to melt is a bit of an issue. The stuff reacts violently with *everything*. You’re not going to keep piranha bath in a shampoo bottle—not unless the shampoo bottle was engineered by James Bond’s Q. Glass would be most appropriate, assuming that you could find a way to seal it that wouldn’t be eaten.

Read the whole thing.

New Airline Security Rules

The foiled UK terrorist plot has wreaked havoc with air travel in the country:

All short-haul inbound flights to Heathrow airport have been cancelled. Some flights in and out of Gatwick have been suspended.

Security has been increased at Channel ports and the Eurotunnel terminal.

German carrier Lufthansa has cancelled flights to Heathrow and the Spanish airline Iberia has stopped UK flights.

British Airways has announced it has cancelled all its short-haul flights to and from Heathrow for the rest of Thursday.

The airline added that it was also cancelling some domestic and short haul services in and out of Gatwick airport during the remainder of the day.

In addition, pretty much no carry-ons are allowed:

These measures will prevent passengers from carrying hand luggage into the cabin of an aircraft with the following exceptions (which must be placed in a plastic bag):

Pocket size wallets and pocket size purses plus contents (for example money, credit cards, identity cards etc (not handbags);
Travel documents essential for the journey (for example passports and travel tickets);
Prescription medicines and medical items sufficient and essential for the flight (e.g. diabetic kit), except in liquid form unless verified as authentic;
Spectacles and sunglasses, without cases;
Contact lens holders, without bottles of solution;
For those traveling with an infant: baby food, milk (the contents of each bottle must be tasted by the accompanying passenger);
Sanitary items sufficient and essential for the flight (nappies, wipes, creams and nappy disposal bags);
Female sanitary items sufficient and essential for the flight, if unboxed (e.g. tampons, pads, towels and wipes) tissues (unboxed) and/or handkerchiefs;
Keys (but no electrical key fobs)

Across the Atlantic, the TSA has announced new security rules:

Passengers are not allowed to have gels or liquids of any kind at screening points or in the cabin of any airplane.

They said this includes beverages, food, suntan lotion, creams toothpaste, hair gel, or similar items. Those items must be packed into checked luggage. Beverages bought on the secure side of the checkpoint must be disposed of before boarding the plane.

There are several exceptions to the new rule. Baby formula, breast milk, or juice for small children, prescription medications where the name matched the name of a ticked passenger, as well as insulin and other essential health items may be brought onboard the plane.

See the TSA rules for more detail.

Given how little we know of the extent of the plot, these don’t seem like ridiculous short-term measures. I’m sure glad I’m not flying anywhere this week.
