RADLEY BALKO: DNA Exonerations.

Freddie Peacock of Rochester, New York, was convicted of rape in 1976. This year he became the 250th person to be exonerated by DNA testing since the technique was first used in 1989. According to a new report by the Innocence Project, those 250 prisoners served a total of 3,160 years; 17 spent time on death row. Remarkably, 67 percent of them were convicted after 2000, a decade after the onset of modern DNA testing. The glaring question: How many more are there?

A lot, is my guess.
