a mexican stole a 6 pack of beer, near by  a white cop suddenly shot the man 7-10 times with out warning and said: he could have had a gun. or something like that. the cop was a racist but you cant tell why from this info alone. by reading this a person can become racist towards whites, the narrator's race, and/or mexicans.
