Re: The 9/11 Conspiracy
They were box cutters, I believe, not knives. And wouldn't it be much more likely, and drastically less retarded, to assume that it was an error on the security's fault?
I know back when I flew long before the terrorist attacks they didn't do a real hardcore check of my carry on luggage, I doubt they'd have found a box cutter if I made an actual effort of smuggling one on a plane. It's just a piece of plastic that houses a tiny, removable razor afterall. Wouldn't be that hard to hide a razor with your wrist watch, or near your belt buckle, or within the fabric of your carry-on bag...especially when the security was much more laxed.
Oh, and that South Park was pretty funny. ; )
