The TSA is about as stupid as an organization could get, they have no idea what to do but to overreact. A little while ago they wanted to set up TSA offices and metal detectors in every small airport and corporate office, to prevent private pilots, and CEOs, from bringing guns and weapons, on board their very aircraft! What, am I going to hijack myself and fly a small airplane/jet into a house? Oh nooooooooo.
I don't think they realize all they are doing is deterring people from flying, thus hurting their own business, if a terrorist really wants to do something they could. Also better hope a terrorist doesn't bring a large hard cover book on board, they could use some of those huge books as a bludgeoning weapon and take over the plane that way. Then we'd have nothing to do on a plane but get drunk and pass out during the flight.
