I'm not an American, but I could have been a visitor enjoying your lovely Country and people at the time, I think people like that should be locked up and the key thrown away !!! Come on, lets get real you Idiot !!! And what about the actors, how desperate are they ??
Somebody could have been killed. If the cops descended upon the scene and things escalated from there, real guns could have been drawn and then fired. The theatre owner should be charged, forced to pay for the cops' time, pay for the 911 call centre staff time (resources which could have been used to respond to real emergencies were expended), refund the patrons' tickets. Not to mention what could have happened if a patron had a heart attack.
