Read the scenario.On March 7, 1965, hundreds of civil rights activists began a peaceful march from Selma, Alabama, to the capitol in Montgomery. They were protesting in favor of voting rights for African Americans. As the marchers crossed the Edmund Pettus Bridge in Selma, they were attacked by state troopers on foot and on horseback. The troopers severely beat and tear-gassed the marchers, even though they did not fight back. The encounter was filmed and shown on national news that night. The public was shocked by the violence of the state troopers. That news coverage was a turning point in the fight for racial justice. Not long after, President Lyndon B. Johnson signed the Voting Rights Act into law.

Read the scenario.The nightly news played a big role in shaping public opinion on the Vietnam War. In the early years of the war, TV coverage centered on battle maps and statistics. The human cost of the war was seldom shown. In the late 1960s, television coverage changed as reporters began to distrust government statistics. Also, images from the Tet Offensive cast doubt on the government’s claim that the United States was winning the war. In 1968, Walter Cronkite, the anchor of CBS Evening News, returned from a tour of Vietnam. He declared his belief that the war would end in negotiation, not victory. Public support for the war began to drop.
