Now I've heard everything!

If I know that motorists coming towards me are going to encounter a hazard which will make them brake sharply, I see it as my duty to warn them about it. It could be a fallen telegraph pole, a cow in the road or a jobsworth with a speed camera. I don't see an iota of difference between them.

I have always done it, and will continue to do so. The CPS should be thoroughly ashamed of themselves, and should concentrate their increasingly scarce resources on prosecuting criminals.
