Many studies during the past few decades have sought to determine whether the death penalty has any deterrent effect on homicide rates. Researchers have reached widely varying, even contradictory, conclusions. Some studies have concluded that the threat of capital punishment deters murders, saving large numbers of lives; other studies have concluded that executions actually increase homicides; still others, that executions have no effect on murder rates. Commentary among researchers, advocates, and policymakers on the scientific validity of the findings has sometimes been acrimonious. Against this backdrop, the National Research Council report Deterrence and the Death Penalty assesses whether the available evidence provides a scientific basis for answering questions of if and how the death penalty affects homicide rates. This new report from the Committee on Law and Justice concludes that research to date on the effect of capital punishment on homicide rates is not useful in determining whether the death penalty increases, decreases, or has no effect on these rates. The key question is whether capital punishment is less or more effective as a deterrent than alternative punishments, such as a life sentence without the possibility of parole. Yet none of the research that has been done accounted for the possible effect of noncapital punishments on homicide rates. The report recommends new avenues of research that may provide broader insight into any deterrent effects from both capital and noncapital punishments.

Forty years and 1,400 executions after the U.S. Supreme Court ruled the death penalty constitutional, eminent political scientist Frank Baumgartner and a team of younger scholars have collaborated to assess the empirical record and provide a definitive account of how the death penalty has been implemented. A Statistical Portrait of the Death Penalty shows that all the flaws that caused the Supreme Court to invalidate the death penalty in 1972 remain and indeed that new problems have arisen. Far from "perfecting the mechanism" of death, the modern system has failed.

Since 1996, death sentences in America have declined by more than 60 percent, reversing a generation-long trend toward greater acceptance of capital punishment. In theory, most Americans continue to support the death penalty. But it is no longer seen as a theoretical matter. Prosecutors, judges, and juries across the country have moved in large numbers to give much greater credence to the possibility of mistakes - mistakes that in this arena are potentially fatal. The discovery of innocence, documented in this book through painstaking analyses of media coverage and with newly developed methods, has led to historic shifts in public opinion and to a sharp decline in use of the death penalty by juries across the country. A social cascade, starting with legal clinics and innocence projects, has snowballed into a national phenomenon that may spell the end of the death penalty in America.
