Journalism, Ethics and Society In a democratic world, journalist have the responsibility of reporting corruption, abuse of power and any other item of information that the public has the right to know. They have a special political purpose to seek the trut h, and resist the pressure to convey distortions. Journalism is indeed a first draft of memory, as Zarecka (1994) states, thatthe elements of the past that are remembered are worth knowing about. Hence journalists must seek to solidify the pieces of information that are deemed to go down in history books, and to conceptualize them by depicting them through mass media.
