Not anywhere, Snowden managed to evade them.
It's the same with an average dim Russian's opinion on Navalny as it is with an average dim American's opinion on Snowden and Assange.
Well not "extradition" in the traditional sense, since Snowden is now a Russian citizen and they don't have an extradition treaty, but hey in a lawless place, anything is possible, they can just ship him to a US-friendly country who will then deliver him the rest of the way.
I wonder if he's got a hiding strategy figured out, with wife and kid(s). Russia's a big place after all.
Or worse. Not say anything other than "get in the car now". It is not like dictators need to explain themselves.
