Too many people think that the "terrorists" are teeming with members and are only capable of obtaining obvious weapons like knives.

We really need to reassess what constitutes a legitimate threat to aircraft and airpots, focus on those things, and let the rest of them go. A loony could go nuts with a knife at a mall. It's just one of those things no one needs to worry about unless they want to spend their lives worrying about all possible sources of harm.
