A few months ago I was waiting at a red traffic light beside a police car in a 40mph zone, heading into a 30mph one . When the lights changed, the police car shot off at about 50 miles per hour. I caught up with it at the next set of lights, noted its registration number and reported it to Luton police.

   They claimed the car was on an emergency call, but I pointed out that it couldn’t have been as it had no blue light flashing and had waited at two sets of lights . So I was told to write to the chief superintendent who replied informing me that the driver couldn’t be traced.

   I was seriously meant to believe that the police couldn’t trace one of their own drivers, even though I’d passed on the time, location and registration details.

   Then one day , as I travelled home at night, I turned into a village off the main road and noticed I was being followed by a police car. I was careful to keep my car at 30 mph, and after a few hundred yards the police must have realised I was aware of their presence. They then committed the crime they were waiting to catch me for, overtaking me and speeding off at about 45 mph. What hypocrites.

   I noted their registtration number and again wrote to their chief superintendant. He eventually replied that he had managed to trace the driver, but that the two officers denied speeding and claimed I had been following them. Two police officers’ word against a member of the public — no chance.
