One of the tools in the hands of the Nazis to terrorize Jews was arbitrary incarceration: the Enabling Act of March 24th, 1933, handed the regime the legal basis for the perfidious institution of “protective custody”: persons deemed to “endanger the security of the people” could be detained without concrete charges. Ostensibly, the policy was aimed at political adversaries. In fact, however, it was frequently used against Jews. The salesman Hans Wilk was among its first victims: in 1933, at 24 years of age, he spent over four months at the Lichtenburg concentration camp. During the November pogroms of 1938, he was among the roughly 30,000 Jewish men incarcerated in concentration camps. On December 16th, he was released from the Sachsenhausen concentration camp in Oranienburg near Berlin. The requirement to report immediately to the State Police in his home town of Potsdam indicated that the harassment was not yet over.
