> Suicide bombers are probably the main vector that TSA helps avoid even if they miss some items sometimes.
Not really, but this is because there are pretty much no suicide bombers anywhere in airports. They are incredibly rare.
But if you're a suicide bomber, by the time you get to the TSA checkpoint you can do a ton of damage inside a terminal during a holiday season when all airports are packed. Until then no one is stopping you.
Why are they rare?
There used to be suicide bombings in the news all the time. Hijackings were the reason they instituted the metal detectors at airports.
Improved security seems unlikely as a reason, given how many tests they fail. Was it just a fad? Did they decide it wasn't getting them what they wanted at a high personal cost? Did they find something more effective?
As far as the terror in terrorism goes, blowing up a plane or hijacking it and flying it into a building is a much bigger impact than blowing up a queue of people. It doesn't need to be rational.
That’s what happened in Brussels.
I was hoping these events could be used to impose fines/jailtime for airlines/airports/security that have queues longer than 5 people, but you know, counter-terrorism can’t mean making life better for the public.
There are many events where you can go that is full of crowded people.
