airport security is not built to prevent evil geniuses to act out a brilliant act of terror macguyver style.

airport security is there to prevent someone to walk onto a plane carrying a boxcutter knife - which they failed to prevent at 9/11.

it's to weed out the idiots, mentally unstable, etc. the times square bomber types.

it relies on underpaid, undereducated personnel. because it exists in reality, which means it is constrained by cost. it also relies on chance and probability. for every post here about sneaking stuff through you have posts of people being held in interrogation or even denied flying triggered by minor details.

and yeah, how many security researchers would post if they got caught? survivorship bias at play.

I typically think Schneier is too cavalier about "security theater", but in this case I agree completely. On the other hand, I don't think that means airport security should be drastically scaled back: There are probably 10x as many dumb potential attackers as smart ones, and it makes sense to be eliminate the easy avenues for the dumb ones while you concentrate other resources on the smart ones. It's also important not to ignore both the intelligence value of security checks as well as their potential forensic value in the event of a successful attack.

TSA actually seems to be making an effort to get smarter about its screening. Trusted passenger programs are expanding dramatically, and I expect the overall burden on the traveling public to decline over time.

That's the point of this sort of thing - it won't. As the article demonstrates, the tools to put together a weapon more lethal than a boxcutter are available within the airport terminal.

Boxcutters are no longer effective tools of terror on airliners. They ceased to be so on the morning of 9/11/2001. Why try to stop them now?

I agree. But I am really tired of having problems because the deodorant I use has 150ml of liquid instead of 100.

This is the point that is always missed when talking about "security theater".

Smart and practiced people can make anything look easy. An attack on an airplane is simply too challenging for the vast majority of people to execute. Is it impossible? No, but almost nothing is impossible.

Making an attack difficult on a plane also eliminates the majority of severally mentally unstable from carrying it out. You can kill 300+ people in one instant, it is impossible to stop the truly motivated and capable (ultra tail risk) attacker, but it is crucial to stop the rest of the tail from casually taking down an airliner.

Don't they also use screening by looking at passengers? Don't know about USA but in my country there's usually a few security people just looking at the people who go through the security check. I suppose they are trained to see nervous people behaving oddly and so forth.

I fundamentally don't understand the danger of "traditional" (box cutters, etc.) weapons getting through airport security. I understand that we need to continue testing for bombs and anything that can actually bring a plane down.

It would obviously be tragic and damaging for someone to attack "defenseless" passengers with "traditional" weapons, but -- in my eyes -- it's not terribly different from a random attack in the street or a shopping mall.

Airline personnel and the typical cohort of passengers would simply never let a terrorist take the cockpit, which effectively removes that entire element of danger. The only super-substantial potential damage stems from an explosive of some sort, not a box-cutter, knife, or anything of the sort.

The cost of TSA (direct and indirect through delays, etc.) is immense, and truly does feel like security theater at this point. I'd be all-for doubling down on bomb-sniffing dogs, behavior analysts, and all that; but this apparent focus on "traditional" weapons seems totally asymmetric to the risk it presents.
