Guilt or Innocence will happen when Manning faces trial.
1) Who cares what Manning pleads? If he pleads guilty, then he goes straight to sentencing. So he pleads innocent. Thus its a moot point. He could even admit his guilt and still plead innocent and have his lawyers argue an affirmative defense.
2) What Manning did? This statement should read what are the charges being levied against Manning. Your statement is a presumption of Manning's guilt.
3) What evidence? That's the nice thing. You have a trial where the evidence is shown in court. With respect to you and every other Tom, Dick and Harry, unless you're in the chain of command, JAG, etc... the odds are you won't see the evidence. Having said that... since the US Military/Government can't keep their lips shut about Seal Team 6, I guess you may have your wish, after the trial.
4) Damages? That's actually irrelevant. But don't take my word, talk to a military lawyer who might explain it to you. (Hint: Someone steals classified material and passes on to an undercover agent. Since no secrets were actually passed on to any foreign agent, one could argue no harm had been committed....)
5) What did he do? Again this is a presumption of guilt and re-iterates #2, and that's what are the charges Manning faces.
6) Dennis the Mennis, former 'boy mayor' of Cleveland, and complete nut job who tried to sue his congressional cafeteria... he has no right or business in this affair. Its a Military issue. He's not in the chain of command. (Thank God for that...)
(Oh and I doubt you'd like what I would say about the UN inspector... you do realize that Manning is a soldier and not some dissident.)
7) I suggest you consult with a military attorney on this one...
Please remember Manning is not a civilian and you can't apply civilian criminal law in a Military case.
