I remember a relative's dog being caught by town officials and euthanized for running deer. He didn't complain--the dog was a project dog from the pound, still early in training, and he was pretty sure it was guilty. A neighbor saw it out chasing deer in his pasture and called the town animal control officer. But it really tore my relative up, because he felt responsible for not training the dog properly or putting up a fence he couldn't get under. (For the record, having met this dog, I'm pretty sure he would have gotten out of just about any fence other than a Supermax facility.)
Seems to me that in today's world some of our songbird populations are of much higher concern than deer, and feral cats should be subject to the same rules as free-running dogs.
As for guides and celebrity hunters and their violations, it seems to be a new low standard--Nugent, Foiles, and now this. One of the reasons I've never considered guiding is that I know there are bad days of fishing, and I don't want to be in the position of being asked by a client to push the limits (legal rules or personal ethics) to put fish in the boat on the bad days.
