Why couldn't he have brought a bomb in when he came back with the guns? Or why couldn't he have pulled up next to the theater and set off a car bomb? Based on the way his apartment was rigged he damn sure had the know how to do so.
People who use bombs tend to do so rationally. By that I mean they calculate risk to themselves in doing this. They often have political motivations.
People who shoot up places do so in large part IMO to fulfill some sort of psychological need, and for the thrill of it.
