Extradition situations are typically run like so: 0. Country A has an extradition treaty with country B. 1. Break a law in Country A that is also a law in Country B but the effects of breaking that law happen in country B. 2. Courts in Country A decide whether the extradition treaty applies. 3. If it's a citizen that breaks the law there are a myriad of ways for Country A to say no. If It's a non-citizen then they get exported with a quickness, usually. Countries like Iceland usually say no to the US, see: Bobby Fischer. Other countries vary quite a lot. Someone correct me if I'm wrong but most countries only extradite their own citizens (sometimes or never) in the case where laws are broken in both countries and there's a ton of political pressure. It's not completely willy nilly though it's worse than I'd like.
