How did the allies deal with a Nazi war Criminals after the war was over?

They put them on trial. Some were sentenced to death. Others were sent to prison. Many got away and have hidden in South America for years. The German government also ignored the war criminals still living and working in Germany. There is a really good recent movie about a lawyer who represented people who had been in concentration camps and he went after the men who took part. It is a true story and on Netflix.
