TSA Response to XKCD “Bag Check” Cartoon

At least this is how the cartoon resonated with me.
But hey, we all look at our own bellies.
I provided that remark just so I could repeat this awesome factoid: a stick of butter has more energy than a stick of dynamite.
With a little work you could turn the butter into a fuel-air bomb. A flour bomb would probably be even easier.
Remember all those news stories a few years back about Dell laptops bursting violently into flames?
However, the expected explosive force of home made liquid explosives is only on the scale of a stick of dynamite, it's certainly less obvious though.
Both explosions randomly placed are unlikely to down a plane, and are likely to be better used breaking into the cockpit than actually downing the plane.
I believe almost a 1/3 KWh high voltage power source could be of much more use than in its explosive force for an organised terrorist attack. However, most anti-terrorism procedures aren't designed to prevent organised terrorists, they're designed to prevent the many more morons with access to explosives.
On the other hand, if the TSA tests 0% of the liquids, the probability of eventual success jumps to 100%...
Edit: on the other hand, I'm not sure it's so infeasible... If 5% of passengers have liquids, and 5% of those get checked, that still seems like a smaller fraction of people than those that get extra security already. Simply having agents open the bottles and smell them (this actually happened to me in china!) would be somewhat effective...
2. Use ctrl+f
"The batteries may be more dangerous than a bottle of water, but they are not more dangerous than a water bottle filled with liquid explosives."
The relevant question is whether the batteries are enough to cause an explosion that could bring down a plane; not whether batteries are more dangerous than water.
What would you do if you were charged with preventing someone from smuggling a weapon onto an airplane, while at the same not not inconveniencing people, and also while being denied, as illegal, the only tool that actually works (profiling)?
They are being given an impossible job. Not hard. Impossible. They don't have a choice except to do security theater.
That's just me. You're right, though, institutionally mandated racism would probably be way more effective.
You are far overestimating how good detectors and searching is. They are already doing all your suggestions, so I guess you are happy with them.
Profiling is effective. Israel does it. If you are a family traveling with kids, they just ask you some questions. Alone? They check more. Arab an alone? Be prepared for a full search. Arab, but with a family? Not as much of a search.
Yes it sucks for the Arabs, no question about it. But it works. And it would never fly in the US. There are many things that work, but have enough drawbacks they will never be used.
You can say profiling has too many drawbacks, and I'll agree with you. But don't say it's not effective.
No, I'm not, which is why I'm doing all the other stuff, too.
They are already doing all your suggestions, so I guess you are happy with them.
Yeah, actually, I think a lot of what the TSA does is completely reasonable and, when executed properly, effective. The fact that some policies are stupid theater does not mean all are.
Profiling is effective. Israel does it.
The United States isn't Israel, we have extremists of all colors and creeds, and terrorist acts here by any one group are rare enough that particular instances can't really be taken as indicators of who will be exclusively trying to do it in the future.
Have people drink from any water bottles they're taking on board.
If someone managed to make a liquid that's simultaneously explosive and non-toxic enough to be ingested, we have bigger problems, namely ingested bombs. Heck, I can just imagine some terrorist swallowing a condom full of explosives, then lighting the detonator wires hanging from his butt.
Maybe then they would have to ban assholes on planes.
The questions the TSA should be asking are:
1.) What is the likelihood that a potential terrorist will use this means of smuggling weapons on board?
2.) How effectively can our screening procedures catch weapons, given that they exist?
3.) How much inconvenience does this cost passengers?
People had little problem with metal detectors and X-rays, because 1.) your clothes and carry on luggage are the natural hiding places for a bomb 2.) the machines will catch most of these instances and 3.) they're not a huge hassle for travelers. But by the time you get down to chucking water bottles because there might be a liquid explosive in them and it might be denser than water and it might be non-polar - really, what are the chances that a terrorist will use that means of smuggling? Compared to, say, overvolting a laptop battery?
For that matter, I think metal detectors may also be obsolete, now that it's fairly easy to make plastic/composite knives and guns.
Indeed, someone apparently did try just this in August of 2006 in the UK- http://www.tsa.gov/press/happenings/311_intl_acceptance.shtm
If we believe the official story 100%, then they merely plotted to do so, but never actually attempted it (they did, however, according to the official story, 'smuggle' non-volatile liquids on in a dummy run, without actually risking taking anything they'd be in serious trouble being caught with).
So, the best case scenario is that no-one 'did try just this'.
That's ignoring all the many holes with the case (that ended up requiring using a legal backdoor to convict them without a unanimous verdict.
Your choice of terminology here makes me a little uncomfortable.
edit: Here's a Schneier post on such a bomber: http://www.schneier.com/blog/archives/2009/09/ass_bomber.htm...
Right. Which is why all self-respecting terrorists won't bother to show you the dumb bottle in the first place. Am I the only one who has, on multiple occasions, checked my bags through the scanner to realize that I'm technically in violation of the "no liquids" rule because I'd forgotten something?
The rule is ridiculous. Just live with it.
What's funny to me is that upon discovering so after getting to the gate I was much more worried about someone finding out I accidentally brought a pocket knife with me, rather than the possibility of someone else with nefarious intentions having also gotten past security with one.
By the way, what's the likelihood of TWO people bringing a knife/bomb on board the same plane? Pretty small, huh? Hence, you should always bring your own bomb to fly safely! ;-)
Like with all TSA stuff, however, it's somewhat at the discretion of the security officer on the spot.
When I emptied my bags after coming home, I had one of biggest "oh shit, phew!" moments of my life, accompanied by visions of Guantanamo.
As someone with more than a casual familiarity with man-portable explosives (some R&D work on remote land mine detection), nobody with any modicum of sense would EVER confuse a bottle of drinking water with a bottle of liquid explosive. The latter have a very low vapor pressure, very different viscosity, and give off very distinctive odors. The most commonly obtained ones are also NOT transparent.
I'm sure they know they could allow most liquids on safely if they gave staff some extra training and put people through enough extra screening. But would the end result be convenient enough? Probably not.

That will never happen. Given the choice between two methods of searches, both of which have equal safety outcomes, people prefer the strip search over the non-invasive one.
Jeffrey Rosen wrote an entire book about this phenomenon; the book is The Naked Crowd. You can read the story, which is on page 1 of the book, via the Amazon sample:

I believe you would be hard-pressed to rouse a lot of righteous indignation over magnetometers.
Uhh, yes. Embarrassment is an irrational, emotional response to a situation. When there is no "situation" - you're no longer in physical proximity to someone with authority over you, who is demanding you do something you don't want to do - there's no embarrassment. I can understand if you object based on principle, but I doubt you're actually embarrassed by it.
There's principles here too, but I don't need to evoke them.

I am certainly afraid that this incident will have an impact on the security searches we'll be subjected to at the airport.
http://en.wikipedia.org/wiki/Korean_Air_Flight_858
Two explosives were used: C4 and about twice as much PLX (a binary liquid explosive) as C4, totaling about 1kg of explosives. The bomb was powerful enough to take down the plane and cause the deaths of all 115 passengers. I suspect C4 was used as a component in order to ensure that the PLX was detonated, because it appears to be a tricky explosive to set off with just a blasting cap.
Regardless, the critique that is being leveled against the TSA is not that such an attack could be successful, but rather that the methods being used to thwart such an attack are wholly ineffectual, with the side effect of causing a great deal of inconvenience, wasting a massive amount of effort, and providing a distraction from more robust methods of solving the security problem.
The funny part is that people generally know security theater like this has jack-all to do with actual security or safety. We just obediently continue to take off our shoes, surrender our nail-clippers, and buy our drinks at the stores in the airport.
Another reason why this discussing annoys me; people always insist on having it on the TSA's terms. Why? They'll win this argument every time. They have more facts and their facts are scarier than yours.
But yes, I'm sure the TSA and its supporters can devise ever-so-many facts about how we have to be protected from water-bottle bombs that fortunately don't require any more special disposal than tossing in a garbage can.
What's your opinion of explosives experts who found the actual plot and chemicals to be used completely ridiculous?
But I'm glad you've convinced yourself that they're wrong about this one way. I'm a convicted TSA skeptic, and you haven't even convinced me, but I'm sure it's fun to be right.
Then don't bleat about what I do and do not know or ramble on about "credibility".
"I'm a convicted TSA skeptic, and you haven't even convinced me"
Yes, you've shown your deep skepticism here, but what made you think I was trying to convince you of anything? I merely pointed out something perfectly true, and you appointed yourself my terribly lazy fact-checker and rhetoric editor.
I'm not going to try to "convince" someone who makes false statements or implications any more than I'm going to have a meeting of the minds with the guy quoting Republican talking points on torture.
Incidentally, what is the right argument to make in your mind? You say it's "retarded" to talk facts and that you're annoyed that anyone's even talking about this issue in the first place, so what's the tptacek-approved rhetoric, here?
Look, all I'm saying is that the both the (lame) comic and the discussion here are missing the point of the actual problem. It's not that 6 ounces of clear fluids could or couldn't be more dangerous than batteries. It's the orgnanizational dynamics that allow debates like this to shape policy.
Seriously, tell me you honestly believe that a highly publicized argument about the safety of laptop batteries on airplanes wouldn't simply get laptop batteries banned at this point.
That would require me to have been actually arguing that argument.
People want security. They will not abandon the desire for security, they will not recontextualize the role of security in their society to your liking. Your only hope is choke down the overweening mania of the security apparatus during periods the public isn't actively panicking.
You point out where security is dumb, inconvenient, and - here's the big point - not making them safer. You prod them out of the cognitive dissonance that keeps them accepting what they already suspect are useless security measures because some authority told them to. You have a hard road ahead of you, but then life is pain.
Guaranteed laugh. Try it. You can say it to the screeners as well, and they'll laugh as well. And it perfectly highlights the absurdity of the security theater we suffer through. Some guy tries to blow up a plane with explosives in his shoes, FAILS, and we all have to take our shoes off now.
See http://en.wikipedia.org/wiki/Security_theater if you haven't heard the phrase security theater before. Not only does the term describe the TSA perfectly, it was actually invented to describe the TSA.
However I'd avoid saying it to them when they are busy or distracted, because then they can't enjoy the humor.
Firstly; I think XKCD was just being amusing....
Secondly: bullcrap. You can make a bang big enough to kill a plane with laptop batteries - the fact you can make a bigger bang with liquids is surely irrelevant. And also it's perfectly possible to change the contents of a battery - no? So put something more explosive in it....
Batteries are very easy to remove.
The reason liquids were banned is because of the evidence someone came up with the suggest there were liquid bombs being planned (and I think one failed attempt) - not a bad response at all! It's the same reason a lot of airports (especially UK ones) ask you to remove your shoes and Xray them.
At the end of the day they can only respond to the perceived or suspected risks - if you really put your mind too it it shouldnt actually be too hard to smuggle a bomb on a plane.
EDIT: by which I mean it is more a case of making people feel safe (by inconveniencing them, basic psycology) as well as causing more inconvenience for a small number of possible potential attacks. The actual security effect is fairly minimal - simply for practical reasons pointed out a billion times over.
EDIT: damn I thought I was being genuinely amusing :(
It's trivially easy to smuggle enough liquids on board an airplane to bypass the TSA's "security" measures. Simply claim it is saline solution or use something like a "beer belly".
Similarly, the TSA's ban of knives on planes is equally toothless. Many fliers (myself included) can attest to having accidentally brought pocket knives on planes without security screening having noticed them. And even a moderately dedicated attacker would find it easy to acquire a ceramic knife capable of passing through a metal detector.
It's a kabuki dance, it's security theater, it increases security not one bit, but makes it more difficult to fly.
"Our policy is irrational, but we're sticking to it anyway in the interests of security theater." "
Having said that, the arguments in that post are bullshit (as evidenced by several comments before this one)
In this day and age that makes them about as enlightened as saying "the TSA uses electricity". They are just doing it because everyone else is doing it there's no credit for original independent thought here.
Sure, most organizations have blogs, but for most they are a write-only place to put press releases.
Anyway....
Yes, the "3-1-1 restrictions" are completely retarded. Yes, people are mostly liquid. Yes, batteries are dangerous. Hollering about that here isn't going to help you, because the TSA people live in an entirely different universe than you do. To them, the 3-1-1 rule is perfectly rational. It's a reaction to an actual threat they had. To abandon the restriction, they have to accept responsibility for the next time liquid explosives are used to destroy a plane. They are never. going. to. do. that. It would be irrational --- from their perspective --- for them to do so.
This TSA response isn't disingenuous. It's exactly what any thinking person expects them to say. So what are we discussing here?
That's not why those signs are there. They're there because it removes the "I was just joking!" defense.
As soon as one of those is discovered at an airport, according to your reasoning about the TSA's rationales, they would have to and should cavity search every passenger.
The real questions underlying a topic like this are:
Why do the people have so little say in their own security?
Why do people accept being separated, rudely interrogated, strip-searched, subjected to (unconstitutionally) secret laws and regulations, etc.?
Why are expert opinions completely ignored?
Just because it's "rational" for the TSA/US Government to cover their asses doesn't mean people shouldn't make a fuss about it. Democracy and liberty vitally depend on people making a (meaningful) fuss.
The administration would get blamed anyway by virtue of being in charge. They've been willing to announce stopping the use of torture (with many in their opposition howling that this will cost American lives), so it's clearly not impossible for them to change policy just because security is the claimed justification for it.
Nobody cares about what the TSA itself supports. The TSA does what it's told to do. The idea is to get enough people annoyed about what the FAA has the TSA do to encourage change in policy. This may or may not be doable, but that's politics for you.
EDIT: emphasis added for the benefit of some poor readers.
Good grief.
3 people were waterboarded. The former administration refused to rule in or out any sort of interrogation technique.
They hardly "stopped the use of torture". Made a political statement, sure. Announced what the limits were, sure. But they didn't stop anything of the sort.
At the same time, reasonable people need to speak up about and work on important issues, because it affects the opportunity cost of those in power. If there is zero (perceived) opposition, it becomes cheaper to create more restrictions.
But can I just suggest that this problem is completely intractable? Given the fact that we've accepted the costs of not having cellphones on planes, or listening to our iPods when the plane is landing, or bringing 6 ounces of fluid onto a flight --- given the fact that society and the economy is still functioning given these meaningless and onerous restrictions --- there is simply nothing in it for the government to removing the restrictions.
As an example of what I was trying to express, in the last German national election, 2% of Germans voted for the Pirate Party, which was running essentially as an interest group for personal freedom and privacy.
The previous grand coalition government had used the specter of child pornography to legislate secret Australia-style black-lists. People stood up by signing a petition against this and risked being labeled "pro-child porn".
The newly formed (more liberal) coalition abandoned this project during their negotiations, with the Chancelor expressly pointing out the surprising 2% success of the Pirate Party.
This is a case where stupidity was being undone, because of civic engagement.
As I said, pick your battles and don't become a cynic. (Not trying to imply you are, just generally speaking). Cheers. :)
Side note: I appreciate a good rant once in a while, so I don't take any issue with your original post.

I don't really understand what you're trying to accomplish here, but whatever it is, you're not helping your case by stating that xkcdsucks is funnier than xkcd. Yes, the humor in xkcd might be extremely nerdy at times, but at least it's not hateful trollery.

If you were talking about that, I rest my case.
On the other hand, maybe you were talking about http://xkcdsucks.blogspot.com/
The author of that is at least trying to say something. As a matter of fact, he's saying a lot, without contributing much.
As for the nick: brilliant deduction ;)
