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.

In 1987, the United States Supreme Court decided a case that could have ended the death penalty in the United States. Imprisoned by the Past: Warren McCleskey and the American Death Penalty examines the long history of the American death penalty and its connection to the case of Warren McCleskey, revealing how that case marked a turning point for the history of the death penalty. In this book, Jeffrey L. Kirchmeier explores one of the most important Supreme Court cases in history, a case that raised important questions about race and punishment, and ultimately changed the way we understand the death penalty today. McCleskey's case resulted in one of the most important Supreme Court decisions in U.S. history, where the Court confronted evidence of racial discrimination in the administration of capital punishment. The case currently marks the last time that the Supreme Court had a realistic chance of completely striking down capital punishment. As such, the case also marked a turning point in the death penalty debate in the country. Going back nearly four centuries, this book connects McCleskey's life and crime to the issues that have haunted the American death penalty debate since the first executions by early settlers through the modern twenty-first century death penalty. Imprisoned by the Past ties together three unique American stories. First, the book considers the changing American death penalty across centuries where drastic changes have occurred in the last fifty years. Second, the book discusses the role that race played in that history. And third, the book tells the story of Warren McCleskey and how his life and legal case brought together the other two narratives.

Michigan is the only state in the country that has a death penalty prohibition in its constitution—Eugene G. Wanger’s compelling arguments against capital punishment is a large reason it is there. The forty pieces in this volume are writings created or used by the author, who penned the prohibition clause, during his fifty years as a death penalty abolitionist. His extraordinary background in forensics, law, and political activity as constitutional convention delegate and co-chairman of the Michigan Committee Against Capital Punishment has produced a remarkable collection. It is not only a fifty-year history of the anti–death penalty argument in America, it also is a detailed and challenging example of how the argument against capital punishment may be successfully made.

An in-depth examination of what life under a sentence of death is like.

In The History of the Death Penalty in Colorado, noted death penalty scholar Michael Radelet chronicles the details of each capital punishment trial and execution that has taken place in Colorado since 1859. The book describes the debates and struggles that Coloradans have had over the use of the death penalty, placing the cases of the 103 men whose sentences were carried out and 100 more who were never executed into the context of a gradual worldwide trend away from this form of punishment. For more than 150 years, Coloradans have been deeply divided about the death penalty, with regular questions about whether it should be expanded, restricted, or eliminated. It has twice been abolished, but both times state lawmakers reinstated the contentious punitive measure. Prison administrators have contributed to this debate, with some refusing to participate in executions and some lending their voices to abolition efforts. Colorado has also had a rich history of experimenting with execution methods, first hanging prisoners in public and then, starting in 1890, using the "twitch-up gallows" for four decades. In 1933, Colorado began using a gas chamber and eventually moved to lethal injection in the 1990s. Based on meticulous archival research in official state archives, library records, and multimedia sources, The History of the Death Penalty in Colorado, will inform the conversation on both sides of the issue anywhere the future of the death penalty is under debate.
