Errol Morris talks with Tink Thompson—the author of the must-read Six Seconds in Dallas—about the photographic evidence of JFK's assassination in this new fascinating video.

From the New York Times:

The Kennedy assassination changed Tink's life. In 1967, he was an assistant professor of philosophy at Haverford, when he published "Six Seconds in Dallas." Short, simple and quietly convincing, it is still one of the best books written about the assassination.

Ten years later, Tink left academia and became a private detective in Northern California. Now he has returned to what has haunted him for 50 years: Frame #313 of the Zapruder film, and our inability to come up with a definitive account of what happened in Dallas.

Tink is publishing a new book soon—Last Second in Dallas—which talks about all this.
