I am stunned at some of the pretzel bending that is going on to justify this shooting, albeit a small minority of the posters. To me this was murder and the shooter should be convicted. If this is allowed in the name of stand your ground, then what wouldn't be? You could shoot someone in almost any situation that becomes confrontational in any way. The women (wife of victim) certainly would have been able to shoot the shooter if she had a gun. She was likely much more threatened than the man/shooter. The guy had just shot her husband.
We have police and laws to deal with assault. The guy could have pressed charges but he never would because under that scenario, if the police responded, they would not have arrested anyone. Maybe a parking ticket. The shove was unnecessary but not criminal I don't think. And why can't he stand his ground. He was being threatened and he responded with a shove. The other guy responded with a gun. If responding with a gun is OK, why wouldn't responding with a shove?
And this idea that you better shoot him quick before he shoots you? Yeah, let's settle everything with duels. What could go wrong with that.
