After the war, Poland saw a few public executions of German and other mass murderers (also Poles). E.g., the one in Gdańsk was witnessed by 150.000 people when 11 members of the nearby death camp`s staff were hanged for their crimes, including 5 women. The hanging was deliberately cruel so that death came slowly, sometimes the victims` agony lasted even a dozen minutes. The crowd cheered and jeered. Loops were tied on victims` necks by former camp mates who had survived the war and Nazi bestiality. It happened in 1946.
I was also amazed to read about it. I thought such lynch-style executions were typical of America of old times. A perfect example of the brutality of war: it makes ALL people turn into beasts sooner or later.
