Joseph Moore sits in a pickup truck outside his home in Jacksonville, Fla., on Tuesday, Dec. 7, 2021. Moore worked for nearly 10 years as an undercover informant for the FBI, infiltrating the Ku Klux Klan in Florida, foiling at least two murder plots, according to investigators, and investigating ties between law enforcement and the white supremacist organization. Moore was not a klansman before working for the FBI, he said. He said he joined because the government approached him, and asked for his help. (AP Photo/Robert Bumsted)
