The fact is that if you're on top of your vermin control hares will likely do well so will need removing or they become a pest themselves. As long as it's done humanely then get on with it. I've been on some massive hare shoots in the past which are done very well and involved 40+ trusted guns using 4 shot catridges. Refrigerated lorry on stand by. Estate makes money. Keeper get a tip. Hare numbers reduced. No problems at all.
