On the subject of the death penalty, there are reasonable arguments to be made on both sides. But even those who support capital punishment in theory must concede that it's perilously difficult to administer it in practice. It's only defensible if there isn't the slightest doubt whatsoever that the person is unequivocally guilty -- and how many cases are that clear?

The documentary At the Death House Door doesn't take a firm stance against the death penalty altogether, but it sure makes a strong case for exercising caution. It does this through the poignant, heart-rending story of Rev. Carroll Pickett, a soft-spoken Texas man who served for 13 years as chaplain at the notoriously execution-happy Huntsville Prison. Here he counseled with 95 prisoners during their final hours, and the experience changed his life.
