It's not supposed to make sense, it's to acclimate us to having our basic human and Constitutional rights violated. These people aren't even law enforcement, they operate under the same premise as a bounty hunter. Exploiting the same loopholes, pretty much, is why they're able to do this. Law enforcement can't even do this to you unless you're being detained and even then, they don't violate you like these TSA goons do.
I've never been on a plane and only been in a terminal once in my life, to see off my aunt. That was over thirty years ago and I have no plans to ever fly. No one would grope me, my wife or my kids like that, I don't care what uniform they wear. I'd beat their ass unconscious, then sue them, the TSA, the airport and anyone else I could think of for sexual battery. The problems is, most people today are spineless cowards who complain later but won't stand up for themselves now.
They'd rather shout down anyone trying to wake them up for fear of being punished because you rocked the boat. A grand social engineering project, if you will. The more they get away with, the further they'll push the boundaries. They've already gone too far, in my opinion. The terrorists have won.
The modern definition of ‘racist’ is someone who’s winning an argument with a liberal.
