In 1965 , Hayden , along with Communist Party USA member Herbert Aptheker and Quaker peace activist Staughton Lynd , undertook a controversial visit to North Vietnam and Hanoi . The three toured villages and factories and met with an American POW whose plane had been shot down . The result of this tour of North Vietnam , at a high point in the war , was a book titled '' The Other Side '' . Staughton Lynd later wrote that the New Left disavowed " the Anti-Communism of the previous generation " and that Lynd and Hayden had written , in '' Studies on the Left '' , " We refuse to be anti-Communist , We insist the term has lost all the specific content it once had . " In 1968 , Hayden joined the National Mobilization Committee to End the War in Vietnam ( " the Mobe " ) , and played a major role in the protests outside the Democratic National Convention in Chicago , Illinois . The demonstrations were broken up by what was later called by the U.S. National Commission on the Causes and Prevention of Violence " a police riot " . Six months after the convention , he and seven other protesters including Rennie Davis , Dave Dellinger , Abbie Hoffman and Jerry Rubin were indicted on federal charges of conspiracy and incitement to riot as part of the " Chicago Eight " , a.k.a. the " Chicago Seven " after Bobby Seale 's case was separated from the others . Hayden and four others were convicted of crossing state lines to incite a riot , but the charges were later reversed and remanded on appeal . The government did not retry the case and thereafter elected to dismiss the substantive charges . United States v.
