Didn't someone mention on another thread that Dave Bulmer or Neal Sharpley were now clamping cars? At the time I saw that posted, not being English, I didn't understand how individuals could be doing this? Are parking authorities privatised in the UK? Or do you need to be a public official to clamp?

Come to think of it, I don't know how clamping (or "booting"; in Philadelphia we call it "the boot" but not "the Denver boot") works here in the US, either, though I do know that towing services are privatized, so you are paying a private company to get your car back. Is that how it works in the UK too?
