The final report of the investigation was made in August, supposedly the matter has been handed over to military prosecutors to decide what kind of a case can be made and what charges will be filed.

I can see where the timing of this is inconvenient, trying to file charges against Marines for massacring civilians at the same time as the verdict for Saddam Hussein for massacring civilians is being appealed.

I'd say that puts the pressure on the prosecution to seek the death penalty.
