I know Russia has no extradition treaty with the US, but do they never extradite for any reason? Hmm, from what I'm reading on Quora "The Russian Constitution protects its own citizens from extradition to a foreign country." Interesting, I didn't know that.

Sounds offensive that one's compatriots could be given to another country to be put on trial.

Not really. If I murder someone while visiting another country it makes sense I'd face justice in the foreign country, where all the witnesses are. Especially if the legal systems are similar.

It becomes more of an issue where one country doesn't trust the legal system of another country.

Brings up a memory of a recent event of an American DUI murder in the UK and leaving before their untrustworthy legal system kicked in.

Well you just need to marry a via operative and you can get away with it too.

You mean like not extraditing that diplomats wife who killed someone in traffic (DUI) and then ran home to the US?

According to Wikipedia she's a Kazakhstani citizen, not Russian.

That's true, but she has spent lots of time living in Russia. At least as of 2019, she refused to tell reporters where exactly she was living.

Sometimes they do. There was a scandal some years ago when they extradited an ex-banker, who is a Russian citizen, which was illegal.

There's an MLAT treaty. It's unlikely she would be extradited, but it's not impossible.

In Kazakhstan

No, she lives in Russia. She also studied in Russia and tried to get Russian citizenship in 2016.
