Yes,the cop should have given better instructions. But, why did the victim rush back into the truck so quickly? Not excusing the policeman for shooting, but that was bizarre.
Whenever I approach a policeman for any reason, I make sure he can see my hands are empty, and I do not get too close, too fast.
The police are rightly cautious of the public.
Why should the police be cautious of the public? Is the public the enemy of the police? Are the public considered to be property of the State and the police there to keep them subdued?
