I don't care if you've been hunting 5 minutes or 50 years, BASIC COMMON SENSE tells you that an immobilized deer from a spine shot needs finished off ASAP! I can't believe anyone is defending him, well when I see the names off those who are, I guess I can.
I could maybe see getting into a situation where you just didn't have the stomach to finish the job, (new & first deer & all & spine shot deer aren't pretty) but to not even consider the fact that the deer needed finished off...I just can't see it, no matter what your hunting experience.
