Civil disobedience is opposing a law that one considers unjust. Martin Luther King Jr. practiced civil disobedience during the Montgomery bus riots when Rosa Parks was arrested for not giving up her seat to a white man. Civil disobedience can also be seen as free speech without the speech part. Civil disobedience positively affects a society when it is demonstrated through non-violent activities. Take for example Greensboro, North Carolina college students who sat at the Woolward's Luncheonette, which was reserved for whites only. The mainstream media at the time was quick to rush to this story and cover it extensively. One photo was captured in which the white students were throwing food at the students sitting at the "white-only" table.
