Doesn't Switzerland have a non-extradition law? How can Roman Polanski be arrested because of an act he committed in the United States?

They do have extradition laws. If he is wanted in California, the State request an extradition order and it is examined by the Federal Office of Justice. These matters are covered by the Federal Act on International Mutual Assistance in Criminal Matters (IMAA, SR 351.1) The sources linked below go into enough detail for a complete answer.

The sites are well written and relatively easy to understand ( for legal matters ).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
