Do American journalists struggle to remain objective post 9-11? How does covering a war for a long period of time affect a reporter's personal life? Do recent communication technologies and social media make it emotionally easier -- or more difficult -- for those who are in the field and those who wait at home? These and other questions will be explored by four panelists, including Scott Johnson, former Newsweek foreign correspondent and bureau chief, who will describe their time in combat zones and how these experiences affected their lives and perspectives.
