And folks wonder why people are opposed to hunting!!!
Any non-hunter even close to being 'on the fence' about hunting would see this and have their minds made up. As in, "where do I sign a petition to ban this?" Wastage is a crime against the resource, but even more damaging/threatening to the heritage of hunting.
I also believe that carcass disposal on public lands - while legal - is equally problematic. Folks running around with binoculars, scopes, and cameras are trying see the birds alive and on display. Seeing them in a carelessly disposed of pile of guts and feathers taints their opinions. If it can be done discretely, that's one thing. Unfortunately, boat launches and public access areas seem to be preferred.
