Vice President Agnew relished his role as the political attack dog for the Nixon Administration. Sequence of four images from an recent Agnew speech, clockwise from top left: criticizes wire service copy, aggressively points and challenges demonstrators, and Agnew hit hard at the hecklers, and finally says, 'they can't talk, they can't listen, and they can't even sing in tune.' Oct. 30, 1970.
