in indianapolis the news of king's death caused concern among representatives from kennedy's campaign and city officials, who feared for his safety and the possibility of a riot. after talking with reporters at the indianapolis airport, kennedy canceled a stop at his campaign headquarters and continued on to the rally site, where a crowd had gathered to hear him speak. both frank mankiewicz, kennedy's press secretary, and speechwriter adam walinsky drafted notes immediately before the rally for kennedy's use, but kennedy refused walinsky's notes, instead using some that he had likely written on the ride over; mankiewicz arrived after kennedy had already begun to speak. the indianapolis chief of police warned kennedy that the police could not provide adequate protection for the senator if the crowd were to riot, but kennedy decided to go speak to the crowd regardless. standing on a podium mounted on a flatbed truck, kennedy spoke for just four minutes and fifty-seven seconds.
