The HSSPF will act as Himmler's regional representative and, in times of emergency, command all the SS and police forces stationed in his jurisdiction.

December 14
SS chief and Chief of German Police Heinrich Himmler passes the Circular Decree on Preventative Crime Fighting by the Police (Runderlass über vorbeugende Verbrechensbekämpfung durch die Polizei), which facilitates the roundup of persons deemed to be: engaging in chronic “asocial” behavior (Asoziale); habitual criminals (Gewohnheitsverbrecher); or making their living from criminal activity (Berufsverbrecher). The German authorities often include Roma (Gypsies) in these groups.

The decree authorizes the German Criminal Police to round up persons suspected of engaging in asocial or criminal behavior without evidence of a specific criminal act, to hold them for an indefinite period of time, and to incarcerate them in concentration camps. By 1943 the German police will send more than 70,000 “asocial” persons and previously convicted criminals to concentration camps. Almost half of them die by the end of 1943.
