Robert Jackson, the chief prosecutor for the United States in the Nuremberg trials, claimed of Nazi Germany:
"To insure the suppression of opposition a secret police force was necessary. In order to eliminate incorrigible opponents, it was necessary to establish concentration camps and to resort to the device of protective custody. Protective custody, Goring testified, meant that:
'People were arrested and taken into protective custody who had committed no crime but who one might expect, if they remained in freedom, would do all sorts of things to damage the German State.' "
