In my opinion it punishes legal people because of a few illegal people. I can't keep a skull I find, because somebody, somewhere, poaches deer and keeps them.
A buddy of mine shot a nice 8 point on the second to last day of the rifle season this year... It was full of puss on it's shoulder and back. So he called the game comission, because they will re issue tags... They told him they would reissue a tag but he had to surrender the entire deer, head included. Because it was the second to last day, and it was the biggest buck he ever shot, he chose to keep it.
