Don't know how he got a hold of the gun you say???!!!?? It's called negligence on the part of the officers. That's the only way this could have happened.
This is why everybody should be up in arms about officer training. It’s obviously insufficient. It takes longer to gain a barbers license than it does to become a cop that gets to walk around with a gun on them...
So the police removes the gun from himself and places it closer to the prisoner. Then, cuffed, with his hands behind him the prisoner is able to get the gun and shoot the police. 😐
