To my knowledge Snowden isn't wanted for questioning over an alleged rape... Edit : Why the downvotes? Edit 2 : Changed from "To my knowledge Snowden hasn't raped anyone..."
And to my knowledge neither has Assange. He has been accused of rape, which isn't the same thing as being found guilty of rape. I accuse you of being a pederast - therefore you should report yourself to the police? No? No. It doesn't work that way.
How else would anyone ever get convicted of a crime if they can just say "I'm not going near the police or a trial until I've already been proven guilty"?
