On May 4 , 1972 , after a ten-day break from writing , Bremer realized it would be almost impossible to assassinate Nixon , and decided that it was Wallace 's " fate " to be his victim , even though his diary entries never showed the same enthusiasm as they did with regard to assassinating Nixon . The following day , he checked out two books from the public library in Milwaukee , both detailing the assassination of Senator Robert F. Kennedy by Sirhan Sirhan : '' Sirhan '' by Aziz Shihab and '' " R.F.K. Must Die ! " '' by Robert Blair Kaiser
