In a dark thaater he was wearing from my understanding a costume as were some other people for the premier.
Lets say you’re in that theater with a gun, you see 4 shots come from one location and one from the other.
What are you going to do?
Start shooting at where the shots are coming from or point the gun and start asking questions.
If you’re not asking questions you’re firing at any place you see shots coming from right?
If you are asking questions than you’re getting shot yourself because he sure as hell won’t be waiting.
Plus what if he had a regular dressed partner? He sees you pointing a gun at his buddy and he just shoots you.
