And so, just because he is jogging, they have a right to stop you with a gun? If it was reversed, would that be ok.
Bottom line, this was NOT OK. If they were so worried, they could of called the police. No, they chose to get into a fight with someone, and went it went bad, they killed him. Maybe not intentional, but they did. And they will lose in a trial for that.
If you are jogging, and two men come at you with a gun, with another one behind you in a car, anyone would be worried.
