You gotta love the TSA. They serve no real purpose, but its a monster too big to kill, staffed by people who desperately cling to the notion they're doing something important. They don't stop hijackings (locking the cockpit door does that), they don't stop bombings (there are much better targets for that, which don't involve killing the bomber), they don't stop weapons (lots of airports outside the US have simple met…

The grunts working for TSA on the floor at airports aren't desperately clinging for the notion that they're doing something important, or working towards some lofty, noble, and/or altruistic goal. It's just a job. They're principally motivated to do this job by the promise of a steady paycheck and decent benefits -- the same motivation that most other people with steady paychecks and decent benefits also have.

You never saw that Reddit thread where the guy who barely got his GED insisted he was a "federal officer," did you?

As far as I know, it's not. You're now specifically told to not take liquid out of your luggage. At least that was the situation when I flew out of London Gatwick last time - they had people going up and down before the scanners admonishing people to leave everything in their bags to avoid delay.

I've noticed every airport is different, and major airports are usually more likely to have the big fancy looking scanners that help keep the crowd moving along, without taking everything out. Smaller airports seem to have less of that tech and are thus often more of a hassle. And yet somehow, airport security staff frequently get impatient when people in line ask whether to remove their shoes, laptop, etc. As if the…

This is a fairly new change - the new scanners are being rolled out "everywhere", but not everyone has them again, and there were some snafu's last summer that caused them all to be decertified within the EU, and at least for a while only scanners from one company had been recertified.

It'll probably be chaos for the next couple of years while this sorts itself out.

Did you drop a sarcasm tag? Anyone can make a fire on a plane as they allow lighters on a plane, and batteries, and any number of flammable objects. None of that is facing any scrutiny nor stopping crazy people from being crazy.

I've heard that cell phones often catch fire on planes, and the crews know how to deal with that. I guess they have to because the odds of one going up are pretty good across so many flights.

Right but to demonstrate that you lied about X they have to demonstrate X. So by the time you're deporting someone for the lie you could just as easily have deported them for the thing itself.

You're making assumptions the thing they lied about and the thing they are being deported for are the same, and quite often the thing you're actually being deported for is not a reason to deport anyone at all. You come to the US and make a social media post saying Trump is a big fat dummy head. You get deported for lying about being in a terrorist organization.

Is that actually a realistic example? I’m having trouble following what’s happening in the US

I'm fine with some liquid potentially being explosives, but the fact that security just throws them all in the same bin when they confiscate them makes me think that not even they believe it makes any sense. Also, why 100ml? Do you need 150ml to make the explosive? Couldn't there be 2 terrorists with 100ml + 50ml? All these questions, so little answers...

Liquids are not explosive, they are assumed to be used to make explosives once onboard. Regarding quantity, hard to find information, I guess they don't want to have a terrorist handbook to making explosives online, but I would assume that 100ml would mean multiple times this amount would not be enough to make an explosive large enough bring down an airplane. In general, considering the overall cost of the measures,…

> In general, considering the overall cost of the measures, I would think that there is a valid reason and that "it does not make sense at first glance so it's just a security theater" does not hold.

What’s your sense of the overall cost of the measures? It’s not clear to me if you’re saying that high or low costs help justify them.

> But somehow also no bombs at sports events or music concerts, or on trains or subways, or courthouses or.... Boston marathon? The Madrid train bombings? 7/7? Ariana Grande? Airport security has been stunningly successful.

But we don't have intense security checks at concerts, trains, or at marathon events as a result, do we?

This proves that intense security checks prevent bombs.

Concerts and things like sporting events in the US typically require any bags to be clear and only be of a certain size. They may also be checked. No outside liquids are typically allowed (mainly to avoid alcohol). Usually people are at least wanded to prevent weapons, but sometimes metal detectors are setup.

i've been to a bunch of concerts here in the netherlands and they do the most basic checks. last time, they checked my wife's purse without a torch (so she could've hidden anything inside) and didn't check anything on me so i got in with two 1g edibles.

I think marijuana is legal in the Netherlands

No successful terrorist attacks on planes going to/from western countries after 9/11/2001, that's a pretty good record. Maybe we can't prove that the security theater was responsible for that, but still, the only planes that were bombed after 9/11/2001 were inside Russia or going from Egypt to Russia.

I have a rock that keeps tigers away. For 30 years I have not encountered any tigers. That’s a pretty good record.

You should market the rock with a track record like that

This just adds confusion as to the purpose of all this. The motivation behind the liquid limits is that there are extremely powerful explosives that are stable water-like liquids. Average people have never heard of them because they aren’t in popular lore. There has never been an industrial or military use, solids are simpler. Nonetheless, these explosives are easily accessible to a knowledgeable chemist like me. The…

After 4 years of Russia/Ukraine, does anyone think that a terror group would take down an airliner with anything other than a drone? Why take any operational risk of actually going through security?

The fact that nobody has flown a drone with a hand grenade gaffa taped to it right into the middle of some politician's security cordon says to me that either a) terrorists are not smart enough to go for the low-hanging fruit (and the Republican terrorism in NI demonstrates this isn't the case), b) it's actually a lot harder to do than that, or c) the intelligence agencies are really, really good at stopping people from doing that, and even better at keeping quiet about it.

I'm going with option C.
