It is really unfortunate that something like that happened to you. One thing those FAMs can do is communicate with the ground! You're actually quite lucky they didn't jail you - that Patriot Act you know, it's a real hoot!
It isn't quite yet common knowledge that people, once entering an airport, surrender all of their civil rights, you have none. It is like entering a foreign country where US Civil Rights laws do not apply, and there is no embassy to turn to for help.
Just another shining example of private corporations being given authority above and beyond the laws of the land.
Truth be told those "bobsy twins" are always easy to spot, so much so that I'm not so sure it's supposed to be a big secret anymore. I've sat next to them on more than several occasions and when you do, just pay attention and you'll see that you are watched like a hawk if you get into the overhead bin to retrieve something from your carry-on. Can anyone guess why?
Glad you got back home safe and sound instead of locked up somewhere with your family still wondering where you are!
