Good move, there probably was no hacking. Actually their unveted IT man probably released the e-mails.
I very much doubt that. The Paks had a tremendous asset in Awan, and if the RATs win, his value goes up substantially. HRC is indebted to Wendy for rigging the nomination and Awan's power becomes enormous.
Awan is not going to do anything to hurt HRC -- he stands to gain a lot if she is elected.
I think Seth Rich was the leak, but maybe the RATs didn't kill him. It might have been the Paks because he may have had more info on other assets they still have. Maybe even info he didn't know he had and they killed him to prevent its release.
Suppose Seth Rich had downloaded info from the DNC server to a USB stick, which is probable because of the known transfer speed. Some of that goes to Wikileaks, but the Paks don't know for sure there isn't more, and if there is more it points to someone in addition to Awan embedded in the RAT congressional caucus. Someone who is still there.
So they kill Seth and retrieve the information. Then they blackmail whoever they have the goods on in the DNC to keep the server out of US hands.
