The last time he climbed on the police car was to tell the crowd of a short-term understanding that had been met with UC President Clark Kerr. Savio said to the crowd, "I ask you to rise quietly and with dignity and go home," and the crowd did exactly what he said. After this Savio became the prominent leader of the newly formed Free Speech Movement. Negotiations failed to change the situation; therefore direct action began in Sproul Hall on December 2. There, Savio gave his most famous speech, on the "operation of the machine", in front of 4,000 people. He and 800 others were arrested that day. In 1967, he was sentenced to 120 days at Santa Rita Jail. He told reporters that " would do it again".
