On the first question, you're very naive if you don't think this happens on a regular basis from opening day of gun deer season to January 15th every season.
Back before they pretty much banned it altogether in Winston county it started about a week before BOW SEASON. Of course they were just "training their dogs". GW was told dozens of times and said he couldnt do anything unless he caught them with a gun. My response was that he need to brush up on the law. The definition of hunting according to the law is shooting, chasing or otherwise disturbing wildlife.
