... and what, exactly, do you think wikileaks should do if a source is murdered?
... and what makes you think Seth rich was a source?
I have no opinion on that, one way or the other. But I do think that Wikileaks should made a definitive statement. There are seven billion people in the world. Saying that Seth Rich was not a souce would not blow the cover of X. Confirming that he WAS a source, however, would be an important public service.
