I wasn’t going to say anything…but WHAT???
No a pro would have accessed the situation, in a theater full of tear gas with people running and scrambling all over and sure as hell WOULD NOT FIRE A SINGLE SHOT. Like stated earlier that “pro” would simply put his life on the line run towards the gunshots and tackle the shooter.
A real trained professional would not put more innocent civilians in harms way by opening fire. No matter how good of a shot they are, in this situation.
