I think it needs more investigation. Revolver found, shots fired from it found in the car drivers house, neighbor stated that "they just started shooting, they weren't very good shots," He was at home. They were attacking him.
Now. Number one the child's family should have left it alone and let the Cops handle it. Number two, the mother should have never threatened the driver of the car. Number three, the driver of the car should have stayed in the house and called the cops, then if they entered the house he would have had more legal standing.
