A off-duty police officer

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.

“This guy must have sc**wed up the settings,” the off-duty officer thought.

A few weeks later, when he received the violations in the mail, he discovered three traffic tickets-each for not wearing a seat belt.
