Better be careful! Kerry and his Democrat cohorts will scream, "No fair! They're Swiftboating us!"
Careful with your facts here. Officers do not receive a DH but rather dismissal (remember Chuck Connors as Lucas McCord having his buttons pulled off and his sword broken). Such a sentence is appealed and appealed and appealed again. It is a federal conviction and would be very public.
I believe that Kerry is hiding some minor embarrassing information in his record or just hiding his record on general principles. Now that isn't to say that his public record should not be carefully examined, something the media (including CBS) has failed to do adequately.
