It is possible that just drawing extra attention to the documentary itself will make more people curious to view Stolen Honor. Then message will get out.
The POWs are very credible when they are allowed to speak uninterrupted. The problem is that they don't ever get the chance to do this.
No argument there, but sometimes they don't have to say anything. There's a SwiftVet/POW ad on that simply shows these guys standing in a group as the camera moves slowly by. Of all of their ads that I've seen, this is the most powerful.
