Our Local police force got very fed up with people using scanners
one night a load of horses were wandering on the local roads
they belonged to a well known local criminal , the head of the clan so to speak
one of the coppers put out a call saying could Jimmy come and get his horses back in the field
and a few minutes later he turned up , denying any knowledge and saying he was passing !!
they did mount a few sting operations, fed up with being listened in on and finding various idiots arriving in cars and getting in the way, a few messages were broadcast of an unusual nature
and those stupid enough to drive along a particular road found themselves stopped, the vehicle searched and equipment removed pending a court appearance
one chap we knew called sillybollocks ( we used his nickname for obvious reasons)
used to drive around late at night listening in to police broadcasts then turning up for a nosey
never sure why as he had a very sexy shapely wife
he was driving about in the early hours listening in, and heard a call, so decided to go and nose
as he went along a narrow road blue light behind him
he had also been smoking waccky baccy
he was cycling for the next 12 months
I think that they were beaten by South Yorkshire Police though
back in the early 90s they broadcast a fake UFO message, then arrested the various idiots who turned up
