He does need to be convicted. He committed murder, plain in simple
This undisciplined and incompetent idiot was sent on a welfare check because someone’s door was open. Instead of calling into the house to see if everyone was okay...he prowled around the house and shot the resident who looked outside to see who the prowler was.
This wasn’t an accident. Because when he didn’t call through the front door as he should have he initiated this. You don’t skip steps in procedure, and jump right ahead to the skulking in the dark with weapons drawn part. You don’t finally identify yourself to the resident as you are pulling the trigger.
Did he pass the REQUIRED psych eval?
If he FAILED the psych eval who hired him?
Charge that person as an accessory to murder before the fact.
It is no safer, and no less negligent, to hire a KNOWN sociopath, give them a badge a gun, and life-and-death power over any random citizen than it would be to throw an enraged rattlesnake into a kindergarten.
Make an example of this person, lest other hiring managers hire the mayor's psycho kid to pull over your daughter!
