@whoever said he was in the military: he wasn't. The authorities were trying to figure out if he had been in the military, because of how he had made those bombs and boobie trapped his house. They called him bombs "sophisticated". Which is pretty weird to me. I mean a guy who doesn't have any military history would make such dangerous explosives. He was going for a phD in neuroscience, the study of the brain. In my opinion, when let loose the irritant gas in the theater, before he shot at the crowd, was pretty risky. I mean, why didn't anyone scream or run? They would've probably thought it was part of the movies. I mean, it WAS the midnight showing. He was all dressed up too, so it was easy for him to hide those guns. He knew how people would react to the gas. And the shooting noise probably blended in with the sound effects of the movie. If people knew that it wasn't the movie, but a real live gunman, maybe many would've made it out uninjured. Thoughts and prayers go out to the victim's families, and RIP to the deceased.
