For some reason, I think wearing ribbons that have not been earned is a crime. It may be UCMJ though, and not applicable in civilian life.
I just don't know, nor is it a huge issue to me, although I understand why people get mad.
(My paltry few medals were, with much pomp and ceremony, long ago pinned to various beloved stuffed animals, when said stuffed animals were injured by hostile fire from the dog. Probably disrespectful, but they are/were my medals, and my daughters stopped crying.)
