|An off-duty police officer, familiar with radar guns, drove through a school zone within the legal speed limit when the flash of a camera went off, taking a picture of his 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 was messed up.
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.
