I don't know. Fortunately, as hard as they have tried to stop this investigation, they haven't been able to. And reading some of the testimony shows they are keeping under wraps some things that could hamper it. Here is a link to more of the testimony. It is a clean pdf.
It is real interesting that the irs removed their email servers to their own buildings from the federal building in 2011.
What needs to be done is things of this sort need to be shouted out within the walls of the internet and everyone else who is willing to listen and look at the body of evidence thus far. It is damning and those on the other side need to realize one day they could be victim to such behavior themselves, if they don't scream for this type of behavior to be stopped.
I used to find this type of video encouraging.
But after watching nothing come of them over the years my optimism has faded.
It'll get swept under the rug and nothing will come of it....just like always.
