Banning as an immediate response
Many theaters banning costumes after Colorado shooting - KPTV - FOX 12
So, this is interesting - theaters are now banning costumes because of this shooter. Again, stupidity prevails. Now, if the "Emergency Exits" had alarms on them so they went off if someone exited through there, maybe some things would have been different. But banning costumes? So the guy was in a costume. He went out the doors and came back in dressed in armor and a gas mask. How would banning costumes stop any of this?
