Peter Bergen is CNN's national security analyst, a vice president at New America and a professor of practice at Arizona State University. He is the author of the new book "United States of Jihad: Investigating America's Homegrown Terrorists."
(CNN)The news that the FBI had investigated the Orlando terrorist, Omar Mateen, in 2013 and 2014 after he made inflammatory comments to coworkers and because he had possible connection to fellow Floridian Moner Abu-Salha -- an al Qaeda recruit who later became the first known American suicide bomber in Syria -- has generated considerable criticism of the bureau. Critics charge that it should have done more to stop Mateen.
