My response to the "I have nothing to hide," or "Don't break the law, and you have nothing to worry about," crowds is the following: If you have nothing to hide, then you should not be opposed to having a "black box" installed in your car. This way, the next time you are pulled over for any reason, the police/highway patrol can just plug into your black box, and if you have exceeded the state speed limit at any point (since it was last read), they can just give you a ticket on the spot.
