So if some random foreign country tries to extradite you, you stay in prison for the duration of the extradition process, even if it takes a decade?

If you keep appealing against it, and if you aren’t trustworthy enough to be granted bail, then yes.

To defend the right of the US to criminalize and punish actions committed abroad by foreign citizens is... well, imperialistic.

Canadian goes to Germany, kills someone, goes back to Canada.

Germany charges him with murder applies for extradition

You think Canada should just say “nah”?

Who's talking about killing? What was Assange's original crime, exactly?
