Well, just based on what’s written here, it sounds to me like the soldier was looking for trouble. We’ll see what the tapes come up with.
Not to pick on you specifically, as several others have said similar things here, but what are you saying? That if you’re disrespectful to TSA agents and cops that you deserve a good beating? That you have no reason to complain if you bring it down on yourself by being a jerk? Last I checked there is no law against being a jerk, and there is no law that specifies a penalty of a severe beating administered on the spot.
