Kev,
Sorry for you mate. Like everything there's good uns and tossers.
I got a good one in an unnmarked car who had me on video at 112mph on a country road, 60 limit, before i cleared off even quicker. He caught me 10 miles later when stopped in a layby for a fag, sowed me the vid and i thought i was done for, banned etc. Very nice copper gave me a fixed penalty. What a result.
However when my warehouse was broken into 3 times in 5 weeks (always saturday night between 8pm and 9pm) i was told by the police that they knew who was doing it but couldn't catch them! and no they didn't have the resources to stake it out on the odd Saturday night.
Also had a case of fraud for £2000 a couple of years ago which they said would take too much time to investigate for what it was worth!!!
Moral of the story pick your crime or hope you don't get a knobhead. I know one long term guy in the police who is sick of the job, masses of paperwork, and CPS, attitude of the courts when villains are nicked and he's just waiting for his pension.
Sorry you got one with no discretion but motoring offences are a very easy nick. Personally if it were me i'd have you beheaded for such a crime coz you've got more hair than me.
