This is why i ring the police when i go on a new permmision, the cranks/concerned caller, are told every thing is as it should be by the police, and no law is being broken. no further action. anti's are deflated straight away and anything they do, could be braking the law ! and that puts the ball firmly in your court as far as the law is concerned. Happy you have sorted it, any more calls from this anti will be put down as "nuisance" by the police.
A definate win for us hunter's, well done and well shot, pity you could not retrieve it
