I personally don't think any of them are guilty. I can see one, maybe two people melting down in the heat of the moment. But eight? No way. And since the first investigation has already concluded that there was no cover-up, I think that bodes well for them. But of course I still worry a great deal about their fate, especially since their chances of a fair trial (court martial) have been adversely impacted.
With Murtha's position on Armed Services and it's Appropriations Committee, he engaged in serious command influence.
If any of these guys are convicted, I will NEVER be able to believe that they were actually guilty.
