My brother was a police officer in New Orleans. He responded to a domestic dispute call and a guy he knew from prior calls rolled into the street in a wheel chair (he was at that point paralyzed from the waist down- and mentally ill). As my brother rolled up in his squad car, the guy pulled out a tech 9 and riddled his car with bullets. My brother never wears a seat belt and was able to duck just in time. A bullet when straight into his head rest.
A shoot out ensued and the guy became totally paralyzed. He died when Katrina hit New Orleans. I always chided my brother that if he shot better the mentally ill guy wouldn't have had to live as a totally paralyzed person for years.
