That would make the most sense that it has to be established beforehand.... just one of those things since I dont know for certain is it possible kind of things. It will be interesting to see if the US cuts some sort of deal with Israel over this because it is safe to say Trump is very very very very very very pissed at Bibi.

I'm not sure whether you can get diplomatic immunity after the alleged crime. The status must have existed beforehand. Still, I'm confident he will be freed. Jonathan Pollard, who I think had dual citizenship, was eventually released despite committing treason against the US, so anything is possible.
