Teasle Was a Veteran Himself

He has a frame behind his desk with three medals including a Purple Heart. While I don't remember any mention of Teasle having served, IMDb says that he did, but it wasn't ever mentioned in the movie. I personally think that mentioning this character point in the film would have certainly added an extra dimension to the story.
