It’s not a matter of training, it’s a matter of being smart. When you tell somebody to stop you can’t shoot them when they stop. He’s complying, he’s indicating he’s no longer a threat, shooting the cooperative is both morally wrong and illegal. He could easily have the guy move to someplace where he can keep an eye on him while he calls the cops, and then stay on the line WITH the cops, they really don’t like walking into a situation where somebody has a gun drawn even if it’s a good guy.
It’s really not that hard. There’s no such thing as shooting to wound, shooting somebody is trying to kill them, period. If you try to kill somebody that’s surrendered already you lose your right to be on the good guys list, period. It’s important to never point a gun at anything you’re not willing to kill, it’s just as important to know when it wouldn’t be a righteous kill, and after they surrendered is WAY off the list.
It’s illegal for a non LE to use deadly force to detain someone in the state of Florida.
He could point the weapon at the guy but cannot shoot unless there is a threat. Such as the kid reaching for a weapon.
