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.

Bringing together the major death penalty cases decided by the U.S. Supreme Court and the legal issues related to the death penalty, this text classifies the cases according to legal issues, provides commentary on the general case law, provides a chart of the cases discussed, and then presents the legal materials in an understandable, easy-to-digest case brief format. Each chapter includes an outline; briefs for cases that include facts, holding, reasoning and opinions; summary and conclusions; and internet resources.

Is capital punishment morally justified? Although the issue generates strong opinions, there are no easy answers when it comes to taking the life of a human being. Supporters of the death penalty believe it deters law-breaking and is the only punishment strong enough for horrific crimes such as child murder and genocide. Opponents argue that it violates human rights and point to its finality in the face of judicial system error and unfairness. This resource presents a fascinating progression of current viewpoints that reflect the many facets of the death penalty debate.

Is the death penalty a deterrent? Is it applied disproportionately to certain ethnic groups? How harsh is life on death row? In this expanded new edition the author examines these and other controversial issues, draws conclusions from the current research, and discusses their implication for social policy. Topics such as capital punishment policies around the world, executions in the United States, public opinion on the death penalty, juries and the death penalty, and economic analyses of the deterrent factor all receive comprehensive coverage. Appendices round out this newly revised and updated text with studies on public attitudes toward rape and capital punishment, and the deterrent effect of executions on the homicide rate in the United States.
