Yea he clearly tried to murder a whole theatre full of people, massacre-style. Can you immagine him trying to plead no guilty in court? "uhm no thats not what meant to do, it was an accident.."
Even if he doesnt get the death penalty, his life is ruined, its over. Isnt he 20 years old? I hope you enjoyed your 20 years on this Earth because you have no more freedom left, idiot.
