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.

This open access book is the culmination of many years of research on what happened to the bodies of executed criminals in the past. Focusing on the eighteenth and nineteenth centuries, it looks at the consequences of the 1752 Murder Act. These criminal bodies had a crucial role in the history of medicine, and the history of crime, and great symbolic resonance in literature and popular culture. Starting with a consideration of the criminal corpse in the medieval and early modern periods, chapters go on to review the histories of criminal justice, of medical history and of gibbeting under the Murder Act, and ends with some discussion of the afterlives of the corpse, in literature, folklore and in contemporary medical ethics. Using sophisticated insights from cultural history, archaeology, literature, philosophy and ethics as well as medical and crime history, this book is a uniquely interdisciplinary take on a fascinating historical phenomenon.

This distinguished constitutional theorist takes a hard look at current criminal law and the Supreme Court's most recent decisions regarding the legality of capital punishment. Examining the penal system, capital punishment, and punishment in general, he reviews the continuing debate about the purpose of punishment for deterrence, rehabilitation, or retribution. He points out that the steady moderation of criminal law has not effected a corresponding moderation in criminal ways or improved the conditions under which men must live. He decries the "pious sentiment" of those who maintain that criminals need to be rehabilitated. He concludes that the real issue is not whether the death penalty deters crime, but that in an imperfect universe, justice demands the death penalty. Originally published by Basic Books in 1979.
