You may be on to something there. It seems to me he managed to injure an unusually high number of law enforcement officers. I don’t think the responding officers had a Rambo/hero complex going or anything. Yet somehow he managed to shoot what, 5, killing one. Could be that was his objective all along.
The press has still not released where the victims were when they were shot. If PP had been his intended target for a mass killing there would have been a blood bath before the first officer even had time to respond.
Not sure if he had propane tanks that he planned on exploding but exploding devices when emergency crews arrive is a not uncommon in such situations.
I think we will find he has more in common with the UniBomber than not.
