A memo from Robert Hughes to Jerome Heilbron dated August 3, 1967. The memo details the negotiations between SCLC and APD to move a Hiroshima peace rally to an alternate route that avoided the lower-income black neighborhoods, ostensibly out of fear of Klan violence. Hughes records the projections of crowd size by the APD to be far lower than those anticipated by the SCLC, and advocated for the recruitment of more crowd monitors for the march.
