Greg, if she had treated it like a roadkill she would have had to confiscate the rack. Maybe she was under the impression that you wanted the rack enough to tag the buck and she allowed that as the best option.
That's not true. He could have bought the rack for $10 a point and saved his buck tag. You really should contact your local representative or the PGC and get a copy of the code so you know what you are talking about.
