AMERICAN TERRORIST: COULD THE '08 MUMBAI ATTACK HAVE BEEN PREVENTED? (2015)

FRONTLINE investigates American-born terrorist David Coleman Headley, who helped plan the deadly 2008 siege on Mumbai. In collaboration with ProPublica, the film — an updated and expanded version of A Perfect Terrorist — reveals how secret electronic surveillance missed catching the Mumbai plotters, and how Headley planned another Charlie Hebdo-like assault against a Danish newspaper.
