Maybe the cops where you are at are different. I've had cops pull me over for flashing my headlights at them (they were driving with no lights), and then ask me in a joking manner "why'd you flash your lights at me?". I point to his headlights, he laughs, then says "oh ok, you can go now" and then laughs to his buddy for shining the light in my face. They seemed high, seriously.
I've just seen more dishonest and abusive cops than upright ones, so that is probably why I have the viewpoint that I do.
