Taking off your belt is asinine. NO ONE LIKE THAT SHOULD BE SECURITY ANYWHERE, NOR SHOULD THEY HAVE AUTHORITY OVER ANYTHING!
You are correct that any security force, corporation, business or individual that takes responsibility for your safety should be held both criminally and civilly liable when they fail to protect that safety. Untill someone sues and wins millions for this, it will never change. You are also correct in assuming that they can only appear to make people "feel" safe with their costumes, attitude problems and radios. And yes, you are getting the runaround.
BTW, Im glad you are still here.
