Michael, wouldn't it be prudent to include arrest warrants for Europeans as well as BND officials who knew about this and were compliant? I won't hold my breath
Germany has a lot to account for before Germans start criticizing the USA. It was the German government who sold chemical warfare devices and materials to Saddam Hussein.
No. As in the US, it is not required to report crimes to the police, except for few severe crimes (for instance murder). So, knowing about a crime and doing nothing is not illegal.
