Part 2 of 3. Lowell Bergman examines the news media, including what some see as a disturbing trend: the jailing of journalists who refuse to reveal their sources. Included: comments from the San Francisco Chronicle's Mark Fainaru-Wada and Lance Williams, who were subpoenaed after reporting on the BALCO investigation, targeting steroids and athletes; ex-Whitewater prosecutor Stephen Bates; the Washington Post's Bob Woodward; blogger Josh Wolf; and former New York Times columnist William Safire.
