It seems pretty clear that the source of most of the smoke related to Clinton is conservative hatchet men blowing smoke out of their nether regions.  Independent fact checkers like PolitiFact tell us that Clinton scores well above average for truthfulness compared to most politicians.  The right wing Clinton Attack Industry have found that they can make any accusation about Clinton, without any facts to back it up, and it will be lapped up and spread around endlessly by the media.  It has come to a point where a ludicrous conspiracy theory such as the idea that Clinton has had people assassinated gets passed on as valid and legitimate.  Seriously, Anthony Weiner's continued existence alone is proof enough that Clinton doesn't actually have people murdered.
