Jim Leavelle had a front row seat to two of the most shocking moments of the 20th Century, serving in the U.S. Navy aboard the USS Whitney when the Japanese attacked Pearl Harbor on December 7, 1941 and serving as a homicide detective for the Dallas Police Department when President John F. Kennedy was killed on November 22, 1963. Leavelle is most famous for being handcuffed to Kennedy assassin Lee Harvey Oswald when Oswald was killed by Jack Ruby two days after President Kennedy was murdered.

In this edition of "Veterans Chronicles," Leavelle walks us through the harrowing events of the attack on Pearl Harbor and the heroism he witnessed that day. He also goes step by step through his involvement with Lee Harvey Oswald on the day Kennedy was assassinated, and what happened that day in the Dallas Police garage when Ruby shot Oswald right in front of him.
