I think this guy's train went off the tracks a LONG time ago. I also think a lot of heads are going to roll that he was not gently ejected from the military before this. THAT is the real scandal here, to me. WTF? Did he "have something" on someone in power lol? Why the hell was he still in the service? Duh.
Interestingly--he was a homicide investigator for 15 plus years--he also said from the beginning of the coverage that "this looks like the work of a lone kook".
Although of course we did have to have a half-joke about "The Manchurian Candidate"...sort of required, at this crazy point in history. I'm sure the conspiracy theorists all over that like a cheap suit, or whatever that phrase is!
ETA: the news report I just watched said that that cop was just nearby doing traffic control when the whole thing went down; she wasn't even SWAT or anything like that. But she heard the shooting and basically headed straight in and fucking confronted him. Wow.
