call the police give them a tour of the estate , show them any lanes or landmarks you can , point out these chaps are keen on scrap metal and fuel theiving as well as wildlife crime . Killing hares is not the way to go . Any keeper with time to sit indoors watching telly has time to be out killing foxes , and thats the point , if your out and about they notice and stay away . If you find coursers inform the police they has dead hares on them , therefore the offence is commited and the police are duty bound to investigate . You dont need to confront these men , remember , turn a blind eye and your a soft touch and theyll be back and while your sat indoors your covers are being disturbed hence putting your job on the line
