That's one that I'm not expert on, but let me just say that this is not a problem unique to the armed forces. There have been many examples in the news of other organizations where people are bullied, harassed and prevented from coming forward.
I think the key in this is to have a body that's completely external to the organization to make a complaint to. If you can do that and if that body can actually influence what's going on in the organization, then I think you have a way of making change. That's about all I'll say on that.
