An in-depth special
The notion that the United States was immune from acts of homegrown terrorism was destroyed on April 19, 1995, when a truck bomb exploded outside the Alfred P. Murrah Federal Building in Oklahoma City, killing 168 people. Hundreds of lives were irrevocably changed by the explosion on, and survivors, rescuers and family and friends of the dead are still grappling with the effects of the worst act of domestic terrorism in U.S. history.
