We should just go back to being apes
At the height of post-9/11 airline paranoia - and even still today - airlines serve your meals with a plastic knife and a metal fork, frown on matches and cigarette lighters, empty out a lipstick tube to search for small hidden....knives...and will persecute without compunction any feckless carrier of a pair of tweezers. I travel frequently, and have had my share of the shit.
So. Someone needs to explain to me how this happens. To paraphrase Michael Moore: Matches and cigarette lighters, not OK; metal knife, not OK; lipstick tube, definitely not OK; but a chainsaw with what looks suspiciously like blood on it? Dude, come on in.
