-Go to the territory of whichever gang you are working for and they will shoot them for you.
-If you only have one bouncy cop-head on the top of the screen and want to get rid of it, simply hide somewhere. In a couple minutes they will be gone.
-If you are being chased by the police and in a car, find a car painting place. Paint your car and the cops will cease chasing you.
-No matter how many cops heads are shown, this will get rid of them in the first level. Head to the church where the level begins. Walk to the tutorial phone and make sure that you activate the tutorial (and the man begins to speak to you). Quickly proceed to the west side of the building (left of the screen). Walk through the opening on the west side wall that leads up to the roof. The cop heads should be gone.
