Do you think you are a fair-minded American? Listen to this story real quick:
A cop has pulled over a 20-year old male who has no license plate on his car. The rap music coming from the car is so loud the cop has to cover his ears as he approaches the car. "License and registration, please!," he yells as the man rolls his window down.
"Here you go," the man says, handing some papers out the window. The cop says, "Do you realize you don't have a tag on the back? Your rear license plate is missing." The mans says, "Aww, naww, it musta fell off somewhere. It's one on the front if you wanna look at that."
The officer confirms the front does have a plate, which matches the registration and the man on the license. He goes back to his cruiser to run the man's plates and name to check for warrants. He gets a hit on his computer that the man has a warrant for felony assault out on him. He calls in to the dispatcher to tell them he'll be making an arrest.
He steps back up to the man's car and says, "I need you to step out of the car and place your hands behind your back." The man pulls out a handgun and shoots the officer 7 times, killing him instantly, and speeds away. He is never caught.
The question is: how do you feel about this? Please take a minute to think about it. What should happen to the man? What about the officer's family; how should they be taken care of? Should policies change instantly?
Now, if you were imagining the cop as white and the suspect as black as most people do, reverse it. Black cop, white suspect, same story. The difference you felt when you did that (or reversed it from whatever you had imagined) is what racism is. It's really that simple.
