I think it is more likely the result of a soft DA office not prosecuting or protecting mentally ill people who threaten their mothers with bombs and other weapons.
Actually, it’s the fault of his mother whose response to the bombing “incident” where he threatened to kill her was to...hire a really good defense attorney. He got the charges drop.
I suspect that Mom probably told the DA she wouldn’t cooperate and therefore they really didn’t have a case. She also probably swore she was going to get treatment for the “kid,” who btw is 6’6”. But since her way of dealing with his illness seems to have been to enable him...when he had been violent and punched people, she had tried to find boxing lessons for him!...that was clearly not going to work.
She reminds me of the mother of the Sandy Hook shooter - who not only knew he was crazy, but bought him the weapons - and then was the first one he killed.
The state is at fault for accepting this deal in the first place, and they obviously never monitored him after that.
And I doubt that the gay issue had anything to do with it. He just knew that the bar was sitting by itself in some grungy part of town, easy to get into, and probably full of people who were likely to be unarmed and couldn’t kill him before he killed them.
