Hmm Not thatan easy question this one. As always it depends how it is done.
The con side:
Stealing game from neighbors
keeping populations to big for the land
increasing risk for disease spread
less of a sport

Thissure sounds bad but then again the proside is:
helps keeping a good control of how much deer there are
helps controlling which animalsto be picked and which to be saved for the future
makes the shots very safe and minimizing the risk for wounding game or shooting at long and unknown distances
makes for a smooth introduction to hunting
helps other species find food

Well in the end I say it should be legal but it sure can be misused like hell. The misuse I blaim partly to the raising costs involved in hunting. The I-pay-so-I-shoot-mentality is a spreading disease.
