I think there is more to this than alot of you realize. I would shoot it no doubt. I would then call the local Game and Fish Commission to come and get it for testing purposes. This deer may have something that would affect you or the rest of the deer in the area. I would want to know what caused him/her to be that way if the food source was good and weather not to drastic. Tag or no tag I still would not put it in the freezer.
