Obtaining Ferguson's approval is crucial to the conspirators, although Farrington proceeds to organize two shooting teams in anticipation that Ferguson will change his mind. Ferguson, meanwhile, watches news reports and becomes highly concerned at Kennedy's increasingly "liberal" direction: action on civil rights, Nuclear Test Ban Treaty, nuclear disarmament.
