STEVE INSKEEP, HOST:
Here's a little-noticed fact about the death penalty. We've heard a big debate about how to execute people - lethal injection, electric chair, firing squad. That debate obscures a little-noticed fact - the number of people executed by any method is way down in the United States in recent years. NPR justice correspondent Carrie Johnson has been covering this story. She's in our studios. Hi, Carrie.
CARRIE JOHNSON, BYLINE: Hi, Steve.
INSKEEP: How far down?
