Eh, ...

Why should a police officer warn you that they are about to clock your speed? I don't understand why they even need to park in an obvious spot or make themselves seen. How is descretely clocking a speeder more unethical then violating the local laws and ordinances. Speeding is illegal even if there isn't a police officer present. If a police officer choses to camoflage themselves in some way -- ok. I don't see how the appearance (or lack thereof) of the officer has anything to do with the speeding offense. I don't see any reason why they shouldn't be able to be descrete. If that is "unethical" while speeding is not "unethical", I question your understanding of ethics.

Chosing to exceed the speed limit is a free will kind of thing. We do it at our own risk.

The thing that gets me is all of the officers getting time-and-a-half for parking next to a construction site, and then never being around when I see cars racing (not speeding, racing) down the highway.
