(T)ERROR is the story of a 62-year-old former Black Panther who now works for the Federal Bureau of Investigation. It is the first documentary to follow a covert terrorism sting as it unfolds. In this short excerpt from the film, we meet “Shariff,” who has been an FBI informant for decades, helping foil several terrorist plots for the complex government agency. With access to both the informant and the target, the film captures the unfolding drama of a sting and Shariff’s suspicion of the FBI’s resolve to accurately combat terrorism. The full-length film broadcasts on PBS on Monday, February 22, at 10 p.m. EST. To stream the full-length film until February 29, 2016, visit the PBS website.
