That is a total red herring.
I don't believe what the Clintons say. I believe what the police, FBI, and other credible investigators say. I believe what the plane crash investigators say about Ron Brown. Etc.
And, further, I just believe in common sense. The idea that the Clintons had someone killed to prevent wikileaks from getting stuff is a looney tunes claim, and your natural inclination should be to disbelieve it until presented with decent evidence. The evidence demanded to believe these sorts of claims is higher.
The thing about the Clintons is there are plenty of things they did that are wrong and are proven like selling the Lincoln bedroom, pardoning Marc Rich, the cattle futures, some of the women stuff etc. Why focus on this nonsense?
