Ok then, why is there still an investigation going on?
This investigation apparently ties into something bigger, that interests the Grand Jury, perhaps it ties into another Grand Jury investigation altogether. Perhaps it has to do with a reporter teetering on the verge of committing perjury to protect a group of government bureaucrats that sought to undermine the government of the US in wartime. Or perhaps it ties into earlier leaks that exposed allied agents such as the asset in the Czech republic in the Ata case, or perhaps leaks ruined ongoing investigations such as the one into the terror charities Benevolence international or the Global relief foundation. Or perhaps it ties into the Oil for Food thing. There could be any number of reasons.
