12 shots from an AR-15 with optics and the cop wasn't injured? Either his sighting was way, way off, he's a completely horrible shot, or ... and who knows maybe this is a possibility, he didn't really want to kill the cop. Maybe he was just suicidal but had a fear of damnation in Hell if he pulled the trigger himself. Or had some weird kind of martyrdom fantasy to act out. Whatever the case, he's clearly not playing with a full deck.
