The long-awaited trial for Aurora, Colorado, movie-theater shooting suspect James Holmes began on Monday, three years after an attack during The Dark Knight Rises left 12 dead and injured dozens of others. The case hinges around Holmes' mental state at the time of the shooting, with lawyers for Holmes say he was “in the throes of a psychotic episode when he committed the acts.” But the prosecution is arguing that psychiatric evaluations found Holmes mentally stable. "He pleaded not guilty by reason of insanity and there were two psychiatrist about a year apart asked to do independent evaluations of him," Distric Attorney George Brauchler said in his opening arguments. "Both of them said the same thing. That guy was sane."
