On Sept. 21 at 7 p.m., Troy Anthony Davis was scheduled to die. I was reporting live from outside Georgia's death row in Jackson, awaiting news about whether the Supreme Court would spare his life.

Davis was sentenced to death for the murder of off-duty Savannah police officer Mark MacPhail in 1989. Seven of the nine nonpolice witnesses later recanted or changed their testimony, some alleging police intimidation for their original false statements. One who did not recant was the man who many have named as the actual killer. No physical evidence linked Davis to the shooting.

Death brings cheers these days in America. In the most recent Republican presidential debate in Tampa, Fla., when CNN's Wolf Blitzer asked, hypothetically, if a man who chose to carry no medical insurance, then was stricken with a grave illness, should be left to die, cheers of "Yeah!" filled the hall. When, in the prior debate, Gov. Rick Perry was asked about his enthusiastic use of the death penalty in Texas, the crowd erupted into sustained applause and cheers. The reaction from the audience prompted debate moderator Brian Williams of NBC News to follow up with the question, "What do you make of that dynamic that just happened here, the mention of the execution of 234 people drew applause?"
