Which special surveillance and security forces were created by Nazis ?

Explanation

Apart from they already existing police in green uniform and the Storm Troopers (SA), these included the Gestapo (Secret State Police) the SS (the protection squads) criminal police and security service. It was the extra consitutional powers of these newly organised forces that gave the Nazi state its reputation as the most dreaded criminal state. People could now be detained in Gestapo torture chambers, rounded up and sent to concentration camps, deported at will or arrested without any legal procedures. The police forces acquired powers to rule with impunity. So, in this way special surveillance and security forces were created to control or order society in ways that Nazis wanted.
