Hot potato
The Swedish prosecutor is just doing her job. But I bet the Swedish government is less than thrilled at the prospect of having to deal with an extradition request from the US.
If he goes to Sweden, I wonder how it'll play into the scenario that's been speculated on whereby Uncle Sam, having grabbed him, then presents a much more serious charge than on the extradition order? It is said that the country that handed him over has a veto on that. Blighty vs Sweden: who would exercise such a veto vs nod through whatever the 'merkins might try?
