An off-duty police officer, familiar with radar speed checking equipment, drove through a school zone within the legal speed limit when suddenly the flash of a camera went off, taking a picture of his car and license plate.

The officer, thinking the radar was in error, drove by again; even more slowly.

Another flash. He did it again for a third time, at an even slower speed. Same result. So, he made a note to himself to contact the traffic department and tell them that their machine wasn't working properly.

A few weeks later, the off-duty police officer received an envelope from the police department containing three traffic citations... each of them were for NOT wearing a seat belt.
