"Doing their job" he says.

More like security theatre. The TSA is a bloated bureaucracy whose only concern is its level of funding from one year to the next. It's a show to prove to the gullible that they're relevant and necessary.
Patting people down does nothing to make anyone any safer. Enough people buy the story that this sort of thing is necessary and effective and they believe the only alternative to being accosted on your way through airport security is to let terrorists roam free. It's a false choice. But the TSA doesn't want you to know that - their survival as an entity relies on people believing "oh well if you say it's for my own protection, why sure!" But the fact is they're giving up their rights and are no more secure.
Where does it end? When does it get to the point where people say "no more!" Because that's the only way it's going to stop. I see you've conveniently glossed over the fact that they're spreading out and assaulting train passengers too now. What's your answer when people have to pass through a TSA checkpoint and have your "freedom scan" a.k.a. colonoscopy at the end of your street before you can drive to work? Don't drive?
And then there are the sheep who buy into it and give up their rights because the man with the cereal box badge assures them it makes them safer.

BAA! I don't know how they do it in the Netherlands, but here in the States there are still enough of us who get pissed off when we're treated like criminals instead of citizens.
