No, the TSA isn't normal. Remember, they've never intercepted one bomb nor ever caught one terrorist. There's no reason at all we have to tell our children to accept being molested for the sake of security theater. One day the TSA will be considered a stain on our history, one that was dismantled in disgust at what we had become. As the cost of sensors and storage approaches nothing, on the other hand, total surveillance looks to be inescapable.
I wish I could be as optimistic.
I've given up. The wealthy always get what they want and screw everyone else.
