From John Stossel: This Friday's 20/20 is about us...fooling YOU. I host 20/20 this week--both Barbara and John Miller have a night off--and I'll use the hour to look at the how we (the media) may mislead you. Sometimes the media distort pictures. I'll show you how. The Communists killed Trotsky and then removed him from Soviet photographs. Now computers make it easier. Remember when some people booed Hillary Clinton at a fund-raising concert after September 11th? MTV replayed the concert, but changed the boos to applause. TV Guide put Oprah Winfrey on its cover, but gave her Ann-Margret's body....
