The part that gets me is that there was a pre-existing crisis, the escaped patient playing in the street, and one guy working to resolve it. Enter the police and instead of helping they shoot the guy trying to solve the crisis. How does anyone enter that situation and interpret the need for violence? It's very difficult for me to imagine much grey area in this particular case.
