vanHorck, whether or not you agree with Nigelh's views on hunting, as an aviator I think you should be concerned about aircraft being used to harass or spy on people minding their own (legal) business.
We have enough problems with the noise abatement crowd as it is, and certainly don't need more reasons for people to want to restrict the use of aircraft because someone did the aerial equivalent of stalking.
That being said, is it even possible to get a restraining order against _certain_ people/aircraft from loitering over you or your property?
