That was a rabid wolf with a warble worm in his head. Unfortunately, the sheep were probably without protection as they were in a theater that did not condone CCW, probably. Most theaters are that way around here. And since us CCW types are law abiding citizens, checked out by the FBI and the local sheriff, trained in the law of CCW, their arms were probably in their cars.
It is a tragic event, obviously a sick crazy that wanted to make a name for himself. But many died and many young children were injured. They will never be able to fry him hard enough to pay for what he has done.
Pray for the families and the jury that will send him off to prison.
