So there was no "mistrial". The Jury gave their verdict of Not Guilty.

Now the US wants to re try those found NG on same charges but not re-try those who have been found guilty (on the other charges) on those charges as well.

If the process were about justice and not just "Convictions of Any Kind at Any Cost so long as Every One is at least convicted of Something ", they would retry every defendant on the same charges for which there was, what they are claiming, a mis trial. The important point was There was No Mis Trial. Defendants all found NG.

If it really is NG on those charges then this is Double Jeopardy.

What is the precedent for higher authorities to intervene in an ongoing matter? Who can petition? There are clear ongoing breaches of the law by the law that should be stopped in their tracks. If convictions result, these men will be dead before any kind of judicial review can occur.
