Introduction

The case for managing errors of justice is most strikingly made for the crime of homicide. This is the most serious of all offenses, and we have better data on homicides than on any other major category of crime. Errors that involve the arrest and conviction of a wrong person are especially critical in cases in which defendants found guilty are eligible for the death penalty; an error of justice could conceivably result in the taking of the life of an innocent person. It was noted in Chapter 1 that over 100 death row inmates were found innocent and released from prison in the United States from 1976 to 2002. As the second of the two quotes that open this chapter makes clear, however, some people find it no less tragic when innocent people are brutally murdered by a prematurely released offender, a phenomenon that the documented evidence suggests has been more common at least over the past 50 years than has the execution of innocent defendants.
