Aurora looked really messed up. There was no way for this guy to buy all the stuff he used, like high-quality body armor, an AR with all the bells and whistles, and top-line pistols like Glocks. He simply could not afford them, even according to reporting.
Couple that with his shell-shocked look in court, and it makes you go, "Hmmmm."

Yeh that and multiple reports of a second shooter (his handler) by witnesses. He was never supposed to be taken alive. The shooter went out the door and went away from the building and sat down between two cars so I guess his handler didn’t have time to finish him off before the cops got him.
