How about pigeonholing it as foul tempered moron who shouldn't have been carrying a gun in the first place? Witnesses have said that it was Reeves who initiated the conflict, Reeves who escalated the conflict, and Reeves who overreacted and shot an unarmed man.
The person who was violating the rules and shining a phone light in front of other people in a dark movie auditorium, started the conflict.
Don’t waste your breath. Anyone trying to excuse this slimeball deserves no attention.
The old dude looked and acted roided out. No possible way his behavior was at all normal or appropriate. It was plain murder.
