You are advocating summary execution, practiced often in Nazi concentration camps.
Summary executions have been practiced since time immemorial. They are not specific to Nazi death camps. Summary execution was a routine punishment in the US Army for desertion in the Civil War. Was General Grant a Nazi? Was Philip Sheridan a proto-Hitler for enforcing discipline?
What was specific to Nazi death camps was summary execution of individuals, not because they committed actual crimes like rape, robbery, assault or murder, but because of their ancestry.
What I have advocated is what was practiced in the US during the San Francisco earthquake, on the frontier in the absence of settled law and order, etc. - namely that if someone is taking advantage of an emergency situation to terrorize and exploit the vulnerable and innocent, you drop them.
This rational approach to law enforcement has as much to do with Nazism as gefilte fish.
