From the link you provided:
Had he shot the burglar on sight inside his home he might have claimed (and quite possibly believed) he was in imminent danger. But once the burglar attempted to flee, it is hard to argue that innocent life or limb was in danger.“I told him to sit on the coffee table, or I’d blow his brains out,” Lembo said.
But that’s when man bolted toward the front door and Lembo shot him in the shoulder.
"That's when I shot him, yes. I shot just like that," Lembo. Just barely missed the side of the wall. Got him in the shoulder. If he'd have sat there, nothing would have happened. But he wanted to leave. And I've had enough of it. I've had enough."
Under the circumstances, I'd hope for leniency. Heat of the moment, sanctity of a man's castle, and all of that. But as we have the chance to reflect outside of the moment, we should not be encouraging nor celebrating the use of deadly force when it was not necessary in the moment to protect innocent life and limb.
