Four indictments for what, lying? And whatever Manafort did before he met Trump. The "lying" happened after the investigation began, so what that say's is that they haven't actually found a legitimate crime. IOW, without the investigation there is really only one potential crime and it has nothing to do with Trump. After one full year, dozens of investigators and millions of dollars spent, Mueller should be embarrassed. He's clearly gonna double down and stay with it until he has at least something, maybe it will be 10, 15 or 30 people indicted for lying - who knows, but they clearly have nothing on Trump.
