If I recall correctly, there's an issue of legality about wearing/displaying a false military award. As I understand it, Kerry displays these in his senate orifice.
Anyone out there know the legal issues involved, if any?
The only diciplinary action that could be taken would be under UCMJ, and, since he is no longer in the military, those laws don't apply to him...unfortunately.
He does, however, have to answer to the laws of decency as enforced by the people--the people who will keep him out of office.
