I refer to Robert Smyth's letter (Write Back, April 26). Today, I had to walk behind two traffic wardens near Dublin Road in Belfast.
They walked past two police cars - one parked on double yellow lines, the other parked on double yellow lines and on a corner. There was no one in either car.
They then proceeded to take a photo of a car that was about one foot on a yellow line. After about five minutes, they put a ticket on the car.
The driver was in the wrong. But why did they not book the police cars? Or are they immune?
