Too bad Germany does not have a death penalty.
There are many ways to punish people.
The Germans COULD sent those slack-jawed aholes on a one-way plane ride to Bangladesh, Cuba, anywhere south of our border, any place in Africa, or anywhere else in Asia.
There is always Sippenhaft or Sippenhaftung-- kin liability, a German term for the idea that a family or clan shares the responsibility for a crime or act committed by one of its members, justifying collective punishment.
So AHOLE'S family could be punished. Interesting idea.
They sort of overused it in the 1930s and 1940s...
