I gave the secuirty theater high marks for absurdity when they banned metal butter knives after 9/11. Of course, the bad guys still had access to forks. Or better yet, breaking a drinking glass or a bottle of duty-free vodka wouldn't result in an edge sharp enough to cut someone's throat, now would it?
Don't get me wrong, I am not advocating banning any of these things. Just pointing out the absurdity of security theater.
