Roman Polanski- No Justice Needed

[TinCow]

The USA has no jurisdiction over anyone who is in Switzerland (even people from the USA are immune from USA law by virtue of being in Switzerland).

Incorrect. The US has jurisdiction over:

1) Anyone who commits a crime inside the United States or on US territory.
2) Anyone who commits a crime against a United States citizen, even if that crime occurred outside the United States.
3) Any United States citizen, regardless of what they have done, where they did it, and who they did it to.

The US has jurisdiction over Polanski under #1. Switzerland's failure to hand him over has nothing to do with jurisdiction, that's an entirely separate issue from extradition.
