The article says he pointed a realistic (i'm thinking airsoft) gun at police. If I was the cop I would have defended myself as well. Perhaps the officers could tell he had a disability, that doesn't stop him from pulling the trigger on a gun.
If you saw what appeared to be a mentally handicap person carrying a rifle around would you not be a little concerned?
This only makes matters worse, someone who obviously doesn't have the capability to think straight is toting a rifle around? This isn't just open carry. He obviously was holding it in his hands, not slinged, because he was able to point it at police officers.His neighbors said it was obvious that Ernest Vassell had a disability, and police should have known.
Now, this was just my opinion. Perhaps you can change my mind
