In the course of a series of amnesties, hitherto-imprisoned war criminals were steadily released back into civilian life. Meanwhile, most of the worst German war crimes—those committed in the East and in the camps—were never investigated. Although a Central Office of Land Justice Departments was set up in Stuttgart in 1956, local prosecutors studiously failed to pursue any investigations until 1963, when Bonn began to pressure them to do so—and to greater effect after 1965, when the Federal Government extended the twenty-year statute of limitations on murder.
