Do you mind the TSA security procedures at airport boarding gates? In principle, I'm opposed but I can't honestly say they bother me. Unless it's really crowded, it doesn't take that long. I don't mind being groped. I can see where some people might but I'm just not that kind. The worst part is taking off my shoes. There used to not be any good way for age challenged individuals like myself to get them back on afterward. I had to awkwardly do it leaning against a wall so that I didn't fall over or just sit down on the floor and do it then lunge ungracefully back on my feet. Now they have chairs and benches at the other end where older travelers can re shoe with a little dignity. So I'm OK with it.
I don't think it does much good though. My carry on stuff is always full of contraband. Either they don't see it or they just don't care. Either way, I'm sure a determined terrorist could raise a ruckus if they wanted to on any flight, anywhere.
I don't think they really want to. If they really did, there would have been some planes blown up. The Department of Homeland Security is a big waste of money, as far as I'm concerned.
