This promises to be a chicken v. egg debate.
It makes me think of the situation where guys of Middle Eastern appearance object and claim victimisation because they get searched at airports. Duh! Who else is likely to be carrying explosives aboard? How many cases have been reported of other people trying to commit suicide and murder by aircraft apart, that is, from the German nutcase who was in fear of losing his job because of failing eyesight and took it upon himself to dive into a mountain? Unfortunately, the rest of us are now saddled with the same travelling inconveniences of searches. It's one of the reason I no longer fly and if I can't go somewhere by car don't bother. No, I am not obsessed with a fear of flying. I have flown quite a lot. As passenger, I hasten to add, in case even that gets twisted.
