What do you think would happen if the shooter in this story were a civilian? Jail time? Life-long jail time? You have no idea if some random person walking by has any connection to a gunshot noise you heard. You know you’re in a “sketchy” neighborhood, and when he runs, your first thought is to shoot him? Seriously? A dude is running from two guys hollering at him in a sketchy neighborhood, so he deserves to be executed? Are. You. Freaking. Kidding. Me?
