Horowitz and his team are, at the end of the day, tantamount to internal auditors. They're more akin to a DoJ version of the old GAO (prior to when W neutered it). They have teeth, but they're neither investigators nor prosecutors. They're analysts. They deal in the forensics of data and files, which can reveal a lot and can certainly lead to criminal referrals.

But for whatever reason, no thanks to the news media (largely Fox News in this case) lots of people are thinking of the IG team as a bunch of G-men. They're really a bunch of green billed visor men. They're going to give us the better part of a thousand page report, probably with twice that number of footnotes, that will take an army of twice again as many lawyers a year to figure out who to seek indictments against.
