Hundreds of active-duty and retired law enforcement officers from across the United States are members of Confederate, anti-Islam, misogynistic or anti-government militia groups on Facebook, a Reveal investigation has found.

These cops have worked at every level of American law enforcement, from tiny, rural sheriff’s departments to the largest agencies in the country, such as the Los Angeles and New York police departments. They work in jails and schools and airports, on boats and trains and in patrol cars. And, Reveal from The Center for Investigative Reporting discovered, they also read and contribute to groups such as “White Lives Matter” and “DEATH TO ISLAM UNDERCOVER.”
