In the predawn hours of April 22, 2018, a gunman clad only in a green jacket and armed with an AR-15 stormed a bustling Waffle House in Antioch, Tennessee. In just four relentless minutes, he murdered four innocent people—Taurean Sanderlin, 29; Joe Perez, 20; Akilah Dasilva, 23; and DeEbony Groves, 21—before a naked hero, James Shaw Jr., wrestled the rifle away, saving countless lives.

In February 2013, American hero Chris Kyle—the deadliest sniper in U.S. military history—set out on what should have been a routine act of compassion.
