I am sure there are borderline situations. A critically wounded deer that runs several hundred yards and is finished off by someone else is such a case. I would hope that decency could kick in. But the OP seemed to be referring to a case where the other 4 forcefully took the deer - and possibly with deadly intimidation. Or worse yet, like when my dad shot a deer that a bunch of rednecks claimed it for their own without even firing a shot. It can get ugly in a hurry when a few guys armed with guns and under the influence perhaps start pretending they are in an old western movie - this type of intimidation via weapon in hand can not be allowed.
