The real problem is that DHS is turning itself into an unauthorized police force, outfitting their minimum-wage, generally uneducated, poorly trained staff with blue shirts and sew-on badges even though they arent officers of any kind. The REAL police are always there, watching. After 9/11 3 things happened that made us more secure.
1: Arming the Flight Crew
2: Stronger Doors to cockpit
3: Americans don't think it's ransom they want
Nothing else needed to be done. A guy got beat to death recently for just SAYING he wanted to blow up a plane. A sad mob reaction to some particularly poorly chosen words, but the by allowing the TSA to turn airports into harrassment centers they have let the terrorists win by making us scared into giving up our own freedom in the name of (false) security. I would rather see dead Americans than cowed and fearful Americans.
PS: I'm in Afghanistan currently, and the Brits wont even let us fly from combat base to base with a knife in our bags...but we can keep our guns and ammo if we promise not to load them...
I watched 6 commandos take forever trying to get through a metal detector, because their missions got cut short and they still had ordinance on them. They kept trying to walk through, and it would beep, and then he'd fish around for a minute and then produce another grenade, knife, or ammo magazine, and hand it to this dude and try again. It would be funny if it wasn't so damn sad.
