No free speech under Hitler and none now:
"A German court on Thursday convicted far-right activist Ernst Zundel and sentenced him to five years in prison for Holocaust denial in a case that underlined Germany's determination to prosecute people who claim the Nazis didn't murder six million Jews.
The 67-year-old Zundel, who was deported from Canada in 2005, was convicted on 14 counts of inciting hatred for years of anti-Semitic activities, including contributing to a Web site devoted to denying the Holocaust -- a crime in Germany.
Zundel, who has also lived in Tennessee, and his supporters argued that he was a peaceful campaigner being denied his right to free speech.
Prosecutors in Germany were able to bring charges because the Web site is accessible there.

Note that he was prosecuted in Germany for things he did quite legally in the USA and Canada.
