Did DWS have Set Rich KILLED because of releasing those e-mails of hers???
My $.02 is that the DNC someone caught on; perhaps knowing he was the only person with such access and a rabid Bernie supporter. JA made it as plain as could be that SR was the leaker (without saying it outright).
DWS knows where the bodies are buried, the DNC and Hillary know about her shenanigans and vice-versa.
Hence, DWS’s brother makes sure the investigation doesn’t go too far.
Either SR’s family is scared, paid off or dumber than a box of hammers.
