If it was me and I was at the checkpoint removing my items from the x-ray machine, I would stay there, but once I have all my belongings and I am headed into the terminal area, if I heard screeners yelling code Bravo, and yelling freeze, I would start walking at a fast pace and disregard any screeners command to freeze.
If they try to blockade me, I will keep walking at my fast pace, and at 6”3” with long legs, I can fast walk at almost a slow trot and will not hesitate to physically walk into one of the screeners if they don’t get out of my way.
Let them call an LEO, I will tell the LEO that as far as I was concerned, they found someone with a gun or possibly a bomb and I feared for my life and wanted to get the hell out of there as fast as possible, I highly doubt that any LEO, upon hearing that excuse will take any action.
I would also ask the LEO if could file a charge of assault against the screener who came into physical contact with me, no screener has any legal authority to physically touch me without my permission, especially once I have left the check point area if I was not the cause of the alarm to begin with. I would leave that decision to the LEO.
Of course there are screeners out there on a power trip who think they are God and expect you to cower at their feet anytime they so demand, remember their motto is we can do whatever we want.
