Army veteran wore a wire, risked his life for 10 years to expose Florida's KKK

For nearly 10 years, U.S. Army veteran Joseph Moore lived a double life -- attending secret meetings and participating in cross burnings while donning a white robe and hood with the Ku Klux Klan in north Florida. But he also wore something else: a wire for the FBI. He helped foil at least two murder plots and exposed Klan members working as law enforcement officers throughout Florida. And his efforts nearly got him killed.
