The interviews with Ed Kemper who committed unspeakable acts are absolutely gut wrenching. The two FBI agents are just beginning to delve into the mind of people who are so complex and so frightening. When they are unable to even offer help to people who are on the front lines in aberrant murder cases, they feel it is paramount that they begin to try to figure out what makes them tick. Of course, the FBI is an old institution, stuck in tradition and often ignorant (in the Seventies portrayed here, certainly) of experimental methods, with an agenda that puts the brakes on risk taking. Bill and Holden are as different as can be; each has his own methodology, but they have become totally absorbed in their mission. They are also under the gun. They are seen as wave-makers that aren't really needed. The speech that Kemper makes in his matter-of-fact way sends chills down the spine, yet there is a glaring logic that we can't deny. Great television, a cut above what we are used to.
