Over 300 million Americans, only around 10,000 gun homicides every year.
The fact that Rich had nothing stolen from him and he was shot in the back is evidence of murder with a seemingly non-street incentive.

2015 - 13 286 people killed by firearms in 2015, 26 819 injured. This data was taken in November in 2015 and, as my source indicates, were likely to rise by several hundred once the final tally was said and done. Numbers do not include suicides.
So many people die annually from gunfire in the US that the death toll between 1968 and 2011 eclipses all wars ever fought by the country. According to research by Politifact, there were about 1.4 million firearm deaths in that period, compared with 1.2 million US deaths in every conflict from the War of Independence to Iraq.
That's 40 000 people shot in 2015. Probably not connected to 40 000 robberies.
Carl Sagan said, "Extraordinary claims require extraordinary evidence." And, while the leading presidential candidate in the American election leaving a string of bodies over her half-century career would be an extraordinary claim, we're not even demanding extraordinary evidence: we're demanding pretty basic evidence.
I don't know if you've noticed, but the internet is full of crazy conspiracy assholes who put together the most insane things into the most unlikely conclusions. This is not the first time they've tried to connect Hillary to contract murder. but unless actual proof is discovered, you are at this moment sounding like any other lunatic conspiracy theorist who just hates Hillary so much that he can't think straight.
Impossible? No. Unlikely? Yes. Proven? Not yet. The only rational response to Seth Rich's murder is: I hope the police are able to conlusively find his killers, whoever they are.
Also, you missed a phantom edit in my last post. It's worth reading considering my comment that started our discussion.
