Hillary never fires the shots herself. She has hired hands.
Conveniently trying to establish an alibi.
There was an article recently on the internet exposing the Democrat machine in I think Colorado trying to persuade a moderate Democrat to get out of the 2018 primary race. The prog wing of the party was trying to fix the primary so their favored candidate would get the nomination. The guy who was doing the arm twisting in that case was none other than Steny Hoyer. There was a recording of the conversation. It’s not too far-fetched to wonder if maybe Kamenetz was under the same pressure but—knowing published details about his personality—he may have told the arm twister, whoever it was, to stuff it. Did he and his wife by chance go out to dinner the night before? Not too many details in the article except for the decision made to head to the fire department instead of the hospital.
