The gang-bangers played this guy. Too bad they didn’t enter his house. Stopping the threat inside is generally more justifiable than warning shots outdoors according to tactical instructors at places like Blackwater Training Center and Gunsite Academy.
Unfortunately when approached by a large number of individuals, such as was the situation in this case, awaiting for entry into the home to fire would have been far too late for this gentleman and his family.
He should have killed as many as he could have in my opinion.
