He placed explosives traps in his apartment, for the first responders to be killed, much like terrorists do in Israel - first explosion, and when help arrives, then second, much bigger, to inflict as much damage as possible, all well timed. Can you call him crazy? what is definition of crazy, if he's cunning monster? BTW, did you notice that his pupils were not as dilated when latest pictures were taken? He's not that insane. Maybe he was on bath salts or read Breivik rantings.
