They haven't improved much since then. The organization has essentially made Security Theater an event with audience participation. Yet they routinely miss threats -- like they have a 95% FAILURE rate at points.

Incidentally, that post is fairly well known amongst the security minded as you see here.

I'm not talking one of those small, spherical smokebombs. No, this was one of those 5" long, 1" diameter sticks, and it was by itself in a pocket of my netbook bag, which didn't have room for much else, so it's not like the xray image would have been confusing.
Seems like tons of other people have had similar experiences.
TSA's impact on safety is largely imagination and wishful thinking.
We prevented future 9/11 style attacks by locking the cabin doors
I think what's really preventing future 9/11 attacks is the attitude of the passengers.
I'm certain of this. The scheme used on 9/11 was a one-and-done affair. It cannot be repeated. We know this because only one hour after the first plane hit the north tower of WTC, that infamous "let's roll" line was overheard on a phone call from Flight 93.
Not only are future attempts at this unworkable, not even the 4th attempt of that day was viable!
Airport screening should be for bombs or other materials that cannot be countered by passenger resistance. Drugs, pocket knives, darts, etc. should be passed through without comment. This would also improve the effectiveness of the screening! With fewer items to be on the lookout for, the screening can be more effective.
After 9/11, there was an overwhelming urge for government to “do something”, and this is the result. If you’re the one to dismantle the TSA, however strong your data is why it should be done, it’ll be your head to roll as soon as a negative event occurs. And so the show must go on.
