It varies from state to state. I'm in Las Vegas NV. and when we go out to watch the Stunters on Sportbikes in empty parking lots the cops don't do anything. It's private property and unless there's signs that say "no tresspassing" the cops can't do a thing! Once, I was at a shopping center chatting with a police officer that I know in the parking lot and we both witnessed a car accident, and he told me he couldn't get involved until we saw the other driver speed off. Then that was all she wrote!
