my take on this.
Rich guy could've explained himself, told the officer he was parked legally, asked him to move, and been on his way.
on the other hand, the cop wen't apeshit on this guy for practically nothing.  the cop moves his foot and lower leg in front of the car after the guy is in the car... the driver would NOT have been able to see that.  the cop did not need to throw him to the ground, pin him, throw him against the car, or beat the shit out of the side of his car.
both are at fault for certain things.  stupid arguments will ensue.
