As early as 1956, Wolters feared the effect that disclosure of the GBI's eviction of Jewish tenants might have on Speer. Wolters wrote to Kempf concerning the denazification proceedings, "I am only anxious about the matter of the clearance of Jew-flats in Berlin. That could be a bullseye. And this is the point to which the defense should direct itself ..." In 1964, Speer mentioned to Wolters in a letter that he would need the "Chronik" as a reference in revising his memoirs upon his release. Wolter's response was to have Riesser retype the entire "Chronik", leaving out any mention of the GBI's involvement in the persecution of the Jews, without telling Speer what he was doing. Wolters later wrote that he did this to correct mistakes, to leave out extraneous matters, and "above all to delete certain parts on the basis of which Speer and one or another of his colleagues could still have been prosecuted. The Ludwigsburg Central office for 'war crimes' was still at work and an end of the persecution of National Socialists was not in sight."
