Since 9/11 we've made it "impractically difficult" to hijack an airplane. The flight deck is behind blast doors, and even if someone did manage to sneak a weapon on board, other passengers would more than likely risk life and limb to hold down anybody who got too uppity. This is the real deterrent to terrorism on an airplane, not the TSA. Yet even though the above came into effect very shortly after 9/11, the public has demanded (and the government has provided) such an extreme overreaction of a response that it borders on insanity. So now it's too difficult for a terrorist to hijack an airplane. Are there any other areas where people are densely packed, and where it would be easy for a terrorist to bring in heavy weaponry? Perhaps the circus of a security line that's supposed to take away said heavy weaponry? This is a problem of our own creation! Honestly, anybody who has thought about it for more than a few minutes should have seen this coming. But if you draw out your conclusions (queue jokes about security lines to get to the real security line), it should also be completely obvious that, short of imprisoning the entire country, security from this sort of terrorism is impossible. Yet we continue to escalate rather than de-escalate! What really scares me is the possibility that we might start to see TSA-like "super" agents armed with assault rifles, just as we see militarization of the police forces in our cities. And we're the ones who are going to suffer for it. Some poor guy is going to get shot while taking apart a stroller or something because it "looked dangerous." The time to put an end to this stuff is now, before it spirals out of control. One could argue that it's too late, and that the situation is already out of control. But I would like to believe that the tragedy at LAX today can give people pause to really think long and hard about what's possible and what's appropriate rather than immediately jumping into overreaction mode again.
