That impinges on the wheelclamping issue. We have all heard horror stories about innocent people being beaten up after straying on to private premises. We have heard of cowboys wheelclamping cars that were parked on private premises by mistake, not releasing those cars for several days and demanding huge ransoms before the wheelclamps are removed. Such activity should not be tolerated in a free society. Yes, under proper licence, wheelclamping is an effective deterrent to illegal parking on private property, but there should be good reason for it.
Friend makes an important point.
Not only does wheelclamping not take place, but I have never employed a wheelclamper, be he cowboy or any other type, in my life. I hope that I shall never need to do so. In Norfolk, we are a relatively law-abiding community. Although fly tipping and the dumping of old cars are an increasing local menace, but I hope that they will never necessitate wheelclamping. A licence will also be required for the work done by a private investigator in undertaking surveillance and investigations to obtain information about another person.
