The story of American-born David Coleman Headley, who become part of the militant group that staged an assault on Mumbai in 2008 has previously been told on “Frontline” (PBS, 10 p.m., check local listings) as “A Perfect Terrorist.” But a new update of the investigation, done in conjunction with ProPublica, shows how intelligence agencies failed to stop Hedley, though he has often been given as an example of a person justifying the government’s unprecedented domestic spying.
