Stabbing People with Stuff You Can Get Through Airport Security

“Use of a pig model to demonstrate vulnerability of major neck vessels to inflicted trauma from common household items,” from the American Journal of Forensic Medical Pathology.

Abstract. Commonly available items including a ball point pen, a plastic knife, a broken wine bottle, and a broken wine glass were used to inflict stab and incised wounds to the necks of 3 previously euthanized Large White pigs. With relative ease, these items could be inserted into the necks of the pigs next to the jugular veins and carotid arteries. Despite precautions against the carrying of metal objects such as knives and nail files on board domestic and international flights, objects are still available within aircraft cabins that could be used to inflict serious and potentially life-threatening injuries. If airport and aircraft security measures are to be consistently applied, then consideration should be given to removing items such as glass bottles and glass drinking vessels. However, given the results of a relatively uncomplicated modification of a plastic knife, it may not be possible to remove all dangerous objects from aircraft. Security systems may therefore need to focus on measures such as increased surveillance of passenger behavior, rather than on attempting to eliminate every object that may serve as a potential weapon.

John Mueller on Zazi

I have refrained from commenting on the case against Najibullah Zazi, simply because it’s so often the case that the details reported in the press have very little do with reality. My suspicion was, that as in in so many other cases, he was an idiot who couldn’t do any real harm and was turned into a bogeyman for political purposes.

However, John Mueller—who I’ve written about before—has done the research:

Recalls his step-uncle affectionately, Zazi is “a dumb kid, believe me.” A high school dropout, Zazi mostly worked as doughnut peddler in Lower Manhattan, barely making a living. Somewhere along the line, it is alleged, he took it into his head to set off a bomb and traveled to Pakistan where he received explosives training from al-Qaeda and copied nine pages of chemical bombmaking instructions onto his laptop. FBI Director Robert Mueller asserted in testimony on September 30 that this training gave Zazi the “capability” to set off a bomb.

That, however, seems to be a substantial overstatement—not unlike the Director’s 2003 testimony assuring us that, although his agency had yet to identify an al-Qaeda cell in the U.S., such unidentified entities nonetheless presented “the greatest threat,” had “developed a support infrastructure” in the country, and were able and intended to inflict “significant casualties in the US with little warning.”

An overstatement because, upon returning to the United States, Zazi allegedly spent the better part of a year trying to concoct the bomb he had supposedly learned how to make. In the process, he, or some confederates, purchased bomb materials using stolen credit cards, a bone-headed maneuver guaranteeing that red flags would go up about the sale and that surveillance videos in the stores would be maintained rather than routinely erased.

However, even with the material at hand, Zazi still apparently couldn’t figure it out, and he frantically contacted an unidentified person for help several times. Each of these communications was “more urgent in tone than the last,” according to court documents.

Clearly, if Zazi was able eventually to bring his alleged aspirations to fruition, he could have done some damage, though, given his capacities, the person most in existential danger was surely the lapsed doughnut peddler himself.

As I said in 2007:

Terrorism is a real threat, and one that needs to be addressed by appropriate means. But allowing ourselves to be terrorized by wannabe terrorists and unrealistic plots—and worse, allowing our essential freedoms to be lost by using them as an excuse—is wrong.

[…]

I’ll be the first to admit that I don’t have all the facts in any of these cases. None of us do. So let’s have some healthy skepticism. Skepticism when we read about these terrorist masterminds who were poised to kill thousands of people and do incalculable damage. Skepticism when we’re told that their arrest proves that we need to give away our own freedoms and liberties. And skepticism that those arrested are even guilty in the first place.

The problem with these arrests is that the crimes have not happened yet. So these cases involve trying to divine what people will do in the future. They involve trying to guess as to people’s motives and abilities. They often involve informants with questionable integrity, and my worry is that in our zeal to prevent terrorism, we create terrorists where there weren’t any to begin with.

Mueller writes:

It follows that any terrorism problem within the United States principally derives from homegrown people like Zazi, often isolated from each other, who fantasize about performing dire deeds. Penn State’s Michael Kenney has interviewed dozens of officials and intelligence agents and analyzed court documents, and finds homegrown Islamic militants to be operationally unsophisticated, short on know-how, prone to make mistakes, poor at planning, and severely hampered by a limited capacity to learn. Another study documents the difficulties of network coordination that continually threaten operational unity, trust, cohesion, and the ability to act collectively. And the popular notion these characters have the capacity to steal or put together an atomic bomb seems, to put it mildly, as fanciful as some of the terrorists’ schemes.

By contrast, the image projected by the Department of Homeland Security continues to be of an enemy that is “relentless, patient, opportunistic, and flexible,” shows “an understanding of the potential consequence of carefully planned attacks on economic transportation, and symbolic targets,” seriously threatens “national security,” and could inflict “mass casualties, weaken the economy, and damage public morale and confidence.” That description may fit some terrorists—the 9/11 hijackers among them. But not the vast majority, including the hapless Zazi.

EDITED TO ADD (11/9): This is the Michael Kenney paper that Mueller cites.

A Critical Essay on the TSA

A critical essay on the TSA from a former assistant police chief:

This is where I find myself now obsessing over TSA policy, or its apparent lack. Every one of us goes to work each day harboring prejudice. This is simply human nature. What I have witnessed in law enforcement over the course of the last two decades serves to remind me how active and passive prejudice can undermine public trust in important institutions, like police agencies. And TSA.

Over the last fifteen years or so, many police agencies started capturing data on police interactions. The primary purpose was to document what had historically been undocumented: informal street contacts. By capturing specific data, we were able to ask ourselves tough questions about potentially biased-policing. Many agencies are still struggling with the answers to those questions.

Regardless, the data permitted us to detect problematic patterns, commonly referred to as passive discrimination. This is a type of discrimination that occurs when we are not aware of how our own biases affect our decisions. This kind of bias must be called to our attention, and there must be accountability to correct it.

One of the most troubling observations I made, at both Albany and BWI, was that—aside from the likely notation in a log (that no one will ever look at)—there was no information captured and I was asked no questions, aside from whether or not I wanted to change my mind.

Given that TSA interacts with tens if not hundreds of millions of travelers each year, it is incredible to me that we, the stewards of homeland security, have failed to insist that data capturing and analysis should occur in a manner similar to what local police agencies have been doing for many years.

TSA Successfully Defends Itself

Story here. Basically, a woman posts a horrible story of how she was mistreated by the TSA, and the TSA responds by releasing the video showing that she was lying.

There was a similar story in 2007. Then, I wrote:

Why is it that we all—myself included—believe these stories? Why are we so quick to assume that the TSA is a bunch of jack-booted thugs, officious and arbitrary and drunk with power?

It’s because everything seems so arbitrary, because there’s no accountability or transparency in the DHS. Rules and regulations change all the time, without any explanation or justification. Of course this kind of thing induces paranoia. It’s the sort of thing you read about in history books about East Germany and other police states. It’s not what we expect out of 21st century America.

The problem is larger than the TSA, but the TSA is the part of “homeland security” that the public comes into contact with most often—at least the part of the public that writes about these things most. They’re the public face of the problem, so of course they’re going to get the lion’s share of the finger pointing.

It was smart public relations on the TSA’s part to get the video of the incident on the Internet quickly, but it would be even smarter for the government to restore basic constitutional liberties to our nation’s counterterrorism policy. Accountability and transparency are basic building blocks of any democracy; and the more we lose sight of them, the more we lose our way as a nation.

EDITED TO ADD (11/12): Follow up by the woman who posted the original story. She claims that the TSA’s video is incomplete, and omits the part where she is separated from her son. I don’t believe her.

Detecting People Who Want to Do Harm

I’m dubious:

At a demonstration of the technology this week, project manager Robert P. Burns said the idea is to track a set of involuntary physiological reactions that might slip by a human observer. These occur when a person harbors malicious intent—but not when someone is late for a flight or annoyed by something else, he said, citing years of research into the psychology of deception.

The development team is investigating how effective its techniques are at flagging only people who intend to do harm. Even if it works, the technology raises a slew of questions – from privacy concerns, to the more fundamental issue of whether machines are up to a task now entrusted to humans.

I have a lot of respect for Paul Ekman’s opinion on the matter:

“I can understand why there’s an attempt being made to find a way to replace or improve on what human observers can do: the need is vast, for a country as large and porous as we are. However, I’m by no means convinced that any technology, any hardware will come close to doing what a highly trained human observer can do,'” said Ekman, who directs a company that trains government workers, including for the Transportation Security Administration, to detect suspicious behavior.

Ass Bomber

Nobody tell the TSA, but last month someone tried to assassinate a Saudi prince by exploding a bomb stuffed in his rectum. He pretended to be a repentant militant, when in fact he was a Trojan horse:

The resulting explosion ripped al-Asiri to shreds but only lightly injured the shocked prince—the target of al-Asiri’s unsuccessful assassination attempt.

Other news articles are here, and here are two blog posts.

For years, I have made the joke about Richard Reid: “Just be glad that he wasn’t the underwear bomber.” Now, sadly, we have an example of one.

Lewis Page, an “improvised-device disposal operator tasked in support of the UK mainland police from 2001-2004,” pointed out that this isn’t much of a threat for three reasons: 1) you can’t stuff a lot of explosives into a body cavity, 2) detonation is, um, problematic, and 3) the human body can stifle an explosion pretty effectively (think of someone throwing himself on a grenade to save his friends).

But who ever accused the TSA of being rational?

Modifying the Color-Coded Threat Alert System

I wrote about the DHS’s color-coded threat alert system in 2003, in Beyond Fear:

The color-coded threat alerts issued by the Department of Homeland Security are useless today, but may become useful in the future. The U.S. military has a similar system; DEFCON 1-5 corresponds to the five threat alerts levels: Green, Blue, Yellow, Orange, and Red. The difference is that the DEFCON system is tied to particular procedures; military units have specific actions they need to perform every time the DEFCON level goes up or down. The color-alert system, on the other hand, is not tied to any specific actions. People are left to worry, or are given nonsensical instructions to buy plastic sheeting and duct tape. Even local police departments and government organizations largely have no idea what to do when the threat level changes. The threat levels actually do more harm than good, by needlessly creating fear and confusion (which is an objective of terrorists) and anesthetizing people to future alerts and warnings. If the color-alert system became something better defined, so that people know exactly what caused the levels to change, what the change means, and what actions they need to take in the event of a change, then it could be useful. But even then, the real measure of effectiveness is in the implementation. Terrorist attacks are rare, and if the color-threat level changes willy-nilly with no obvious cause or effect, then people will simply stop paying attention. And the threat levels are publicly known, so any terrorist with a lick of sense will simply wait until the threat level goes down.

Of course, the codes never became useful. There were never any actions associated with them. And we now know that their primary use was political. They were, and remain, a security joke.

This is what I wrote in 2004:

The DHS’s threat warnings have been vague, indeterminate, and unspecific. The threat index goes from yellow to orange and back again, although no one is entirely sure what either level means. We’ve been warned that the terrorists might use helicopters, scuba gear, even cheap prescription drugs from Canada. New York and Washington, D.C., were put on high alert one day, and the next day told that the alert was based on information years old. The careful wording of these alerts allows them not to require any sound, confirmed, accurate intelligence information, while at the same time guaranteeing hysterical media coverage. This headline-grabbing stuff might make for good movie plots, but it doesn’t make us safer.

This kind of behavior is all that’s needed to generate widespread fear and uncertainty. It keeps the public worried about terrorism, while at the same time reminding them that they’re helpless without the government to defend them.

It’s one thing to issue a hurricane warning, and advise people to board up their windows and remain in the basement. Hurricanes are short-term events, and it’s obvious when the danger is imminent and when it’s over. People respond to the warning, and there is a discrete period when their lives are markedly different. They feel there was a usefulness to the higher alert mode, even if nothing came of it.

It’s quite another to tell people to remain on alert, but not to alter their plans. According to scientists, California is expecting a huge earthquake sometime in the next 200 years. Even though the magnitude of the disaster will be enormous, people just can’t stay alert for 200 years. It goes against human nature. Residents of California have the same level of short-term fear and long-term apathy regarding the threat of earthquakes that the rest of the nation has developed regarding the DHS’s terrorist threat alert.

A terrorist alert that instills a vague feeling of dread or panic, without giving people anything to do in response, is ineffective. Even worse, it echoes the very tactics of the terrorists. There are two basic ways to terrorize people. The first is to do something spectacularly horrible, like flying airplanes into skyscrapers and killing thousands of people. The second is to keep people living in fear. Decades ago, that was one of the IRA’s major aims. Inadvertently, the DHS is achieving the same thing.

Finally, in 2009, the DHS is considering changes to the system:

A proposal by the Homeland Security Advisory Council, unveiled late Tuesday, recommends removing two of the five colors, with a standard state of affairs being a “guarded” Yellow. The Green “low risk of terrorist attacks” might get removed altogether, meaning stay prepared for your morning subway commute to turn deadly at any moment.

That’s right, according to the DHS the problem was too many levels. I hope you all feel safer now.

Here are some more whimsical designs, but I want the whole thing be ditched. And it should be easy to ditch; no one thinks it has any value. Unfortunately, if the Obama Administration can’t make this simple change, I don’t think they have the political will to make any of the harder changes we need.

Court Limits on TSA Searches

This is good news:

A federal judge in June threw out seizure of three fake passports from a traveler, saying that TSA screeners violated his Fourth Amendment rights against unreasonable search and seizure. Congress authorizes TSA to search travelers for weapons and explosives; beyond that, the agency is overstepping its bounds, U.S. District Court Judge Algenon L. Marbley said.

“The extent of the search went beyond the permissible purpose of detecting weapons and explosives and was instead motivated by a desire to uncover contraband evidencing ordinary criminal wrongdoing,” Judge Marbley wrote.

In the second case, Steven Bierfeldt, treasurer for the Campaign for Liberty, a political organization launched from Ron Paul’s presidential run, was detained at the St. Louis airport because he was carrying $4,700 in a lock box from the sale of tickets, T-shirts, bumper stickers and campaign paraphernalia. TSA screeners quizzed him about the cash, his employment and the purpose of his trip to St. Louis, then summoned local police and threatened him with arrest because he responded to their questions with a question of his own: What were his rights and could TSA legally require him to answer?

[…]

Mr. Bierfeldt’s suit, filed in U.S. District Court in the District of Columbia, seeks to bar TSA from “conducting suspicion-less pre-flight searches of passengers or their belongings for items other than weapons or explosives.”

I wrote about this a couple of weeks ago:

…Obama should mandate that airport security be solely about terrorism, and not a general-purpose security checkpoint to catch everyone from pot smokers to deadbeat dads.

The Constitution provides us, both Americans and visitors to America, with strong protections against invasive police searches. Two exceptions come into play at airport security checkpoints. The first is “implied consent,” which means that you cannot refuse to be searched; your consent is implied when you purchased your ticket. And the second is “plain view,” which means that if the TSA officer happens to see something unrelated to airport security while screening you, he is allowed to act on that.

Both of these principles are well established and make sense, but it’s their combination that turns airport security checkpoints into police-state-like checkpoints.

The TSA should limit its searches to bombs and weapons and leave general policing to the police—where we know courts and the Constitution still apply.
