Also, security has ALWAYS been theater. It’s only personal self-defense that you can rely on. It’s the belief people hold that somebody will “punish” them if they do wrong that stops them. Not too many people have security guards physically protecting them from crazies. It’s just the illusion that makes us feel warm and fuzzy, and inhibits the crazies from touching us regular folk.
Get yourself a bodyguard, and when asked to go through someone else’s silly security rigamarole, have your bodyguard frisk them first. See how much theater you get to watch from the front row then.
