I don't think you can say for sure this deer wasn't taken care of. It's gutted, which, with the temps being what they have been, the meat should be fine. As for displaying the deer, I don't think it hurts as much as some think. In fact,the fact that we hide our deer all the time, we are killing the culture. Let a kid see a dead deer now and then. Heck, he/she may end up a hunter. I remember the first time i saw some hunters in Idaho with 2-3 dead deer, I was shocked. Being from Tacoma, and not coming from a hunting family, it was an eye opener.
If you're worried about the anti hunting segment getting ammo, then you probably shouldn't put pictures on websites, since they are using those against you, too. Heck, when my kid was in kindergarten, I got permission from the teacher to let him bring horns to school, along with some photos. The more we expose and tell our story, the better. Be proud that you hunt, and stand up to the *censored*es that want to take it away.
