Stupid plod!

You would think that, in view of all their recent bad press, the police would think twice before doing anything to add to their woes, but no apparently.  A newly-wed couple in Dorset chose to be driven to their reception in a replica of the Dodge car used in the old US TV series "The Dukes of Hazard".  As the car passed some waving well-wishers, the driver sounded the Dixie air-horn for which the original car was famous.  A little further down the road, the car was pulled over by the police. Despite the fact that it was clear that this was a wedding couple on the way to their reception, the police issued the driver with a ticket, and he will be summoned to attend court,  It seems the horn is illegal (why??) but surely this was a case where common sense demanded that they use their discretion and let them go on their way with a warning (and good wishes would have been nice). But then, the words common-sense and police are sort of mutually exclusive, aren't they?
