TSA at football games is only a issue if you go to football games.
If a TSA thug/moron stops you without a real cop to back-up the quasi-legality of the stop, how much fun do you wish to have at the TSA's expense is what you should ask yourself. It seems that real LE is finally accepting the fact that courts, and more importantly juries, are not gunna put up with obviously "bad LEO" behavior. What do you think a court or jury is gunna do to the TSA, who ain't really cops to begin with, knowing what we know today about TSA thug/moron behavior?
I'm not too worried about the TSA. I don't play in their sand box and they don't play in mine.
