Crikey ANW, that was quite a post!
I don't particularly object to professional pilots representing lawful authority enforcing the law through aerial surveillance.
I do object to amateur pilots representing extremist groups enforcing their own personal agendas through vigilanteism and using aircraft to harass other citizens.
Without even wanting to get started on the pro/anti hunt debate, I think this sort of vigilante air force is a recipe for disaster and I hope that the police, CAA, and all responsible members of the aviation community would stamp hard on this sort of activity before it becomes commonplace.
