I was "selected" for further security inspection on the way back. The guy was quite professional, clearly telling me every time he had to touch me. I still think it would be reasonably easy to get a non-metallic weapon on a plane, simple to get the equivalent of brass knuckles, and can think of a way to obtain a gun. The equivalent of 9/11 wouldn't happen due to the Instapundit "pack, not a herd" meme, not due to the security guys confiscating fingernail clippers. Unless terrorists specifically targeted a plane with few passengers. Hmm.
