NOVA: "MIND OF A RAMPAGE KILLER"
PBS, 9:00 p.m. ET
In terms of documentary subject matter, is it possible there’s too much of a bad thing? Last night, Frontline devoted itself to a profile of mass murderer Adam Lanza and his mother, his first victim. Tonight, Nova looks at the psychology that may explain, if only partially, the motivation of Lanza and other rampage killers. But coming in the heels of Frontline, is this a well-timed follow-up – or its own type of overkill? Check local listings.
