Ten to one the victim was white.
Blacks being loud and rude during a movie to irritate neighboring whites is pretty common.
I personally know of a white couple who was brutally attacked in a movie by blacks when the guy just politely asked them to please put out their cigarette as no smoking was allowed.
The management ignored the smoking because they were intimidated by similar behavior in the past and just let it ride.
My friend thought if he would just ask them nicely they would obey the rules.
Big mistake.
