Any question answered...

: if all that's in front of them is a minor offence then they should go looking for a more serious one.

ftfy, and I don't imagine they'd need to look hard or for long.

So no police officer should ever do anything about any minor offence ? I expect the people who let their dogs crap on the pavement and don't bother to pick it up would agree with you.

: Anyway, a bicycle carrying this sticker at this time is merely an indicator that the rider is cynical about the performance of Sky in the Tour, since it is the term used by no less a figure than our greatest living roadman and multiple Olympic gold medallist B.Wiggo.

I'm not arguing that it's right that it should be an offence to have a Scunthorpe Bicycle with some of the letters rubbed off, just that given that it is (which I'm also not certain of) then the officer is right to deal with it.
