I think most of you have missed the point here - the guy who gets prosecuted is the Game-keeper - and quite right too but he is almost certainly acting on behalf of the land-owner.
In these cases the fines are probably paid by the (wealthy) land-owner and are a trifle in comparison with the money brought in by the "shooting" brigade.
I think that the time has come for the land-owner to be brought to book as well. The possibility of custodial sentences for land-owners would soon have them discouraging their game-keepers?
Look at last years fires on the moors in the Forest of Bowland which wiped out Harrier nests - an accident? I think not.
