Explanation:
When two home-grown terrorists detonated a truck bomb in front of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995, killing 168 people, it was, at the time, the biggest terror attack in U.S. history. The event set off the nation’s most massive F.B.I. manhunt, surpassed only by the 9/11 terror-attack investigations six years later. Oklahomans still live with the fallout.
