Caught by a speed camera

When a police officer operates a radar unit to check speeding cars, he is usually trained and certified to operate a radar unit and to testify in court concerning the readings it obtained ("Not so fast," Nov. 20).

Usually, the radar unit is calibrated at the beginning of each shift with a tuning fork. So how can a stationary radar speed camera operate 365 days a year in extreme heat and cold and still be accurate? This does not make any sense.

I bet if the speed cameras were not producing great numbers of tickets, it would make your head spin to see how fast the technicians were out checking each unit.
