The part that really gets me is there seems to be a kill on sight order. I mean sure he needs to be put down but the LAPD seem just a bit too anxious to make it happen as fast as possible and without giving him a chance to speak anymore.
Nutjob might have a legitimate gripe. Too bad he decided to shoot innocent people in some bizarre attempt to justify his claims.
That is a serious problem and the very reason why he has sympathizers.
There is not a "shoot on sight order", but if he attempts to flee or escape, rather than surrender when approached, deadly force is justified.
