...when they used slave labour, the same sort of thing with the Swiss bank accounts - it was illegal at the time under international law. Salvery though sad and a very bad thing was legal at the time, it's like if it were made illegal from tomorrow to use the SN "Wads" it would go against common sense to arrest you for having used it in the past. It would be even worse to arrest your great granchildren for your use of it when it was still legal.
