Look, why would anyone go to the trouble of attaching a poison or sedative behind a BH. It makes more sense to just use a dart tipped arrow, less tissue damage, less pain for the animal, less accident prone, etc. (IF ALL THIS WAS LEGAL). I would not use it as I do not want to lessen the experiance for myself. Thumping a booner in the hindquarter with a dart and watching it have a heart attack is not my cup of tea. Picky I know
But it is semantics as it is not legal. For limited use in very urban settings I can see a point for it but only a weak one. A proficency test before the hunt is issued to keep out the suedo-hunters does a pretty good job, and 'normal' (not counting the crazies) people generally just want the deer gone when they eat thier petunias. The vast majority of americans are not anti-hunting.
