The Problem With Assumptions: Revisiting “The Dark Figure Of Sexual Recidivism”, Tamara Rice Lave, Jj Prescott, Grady Bridges Jun 2021

The Problem With Assumptions: Revisiting “The Dark Figure Of Sexual Recidivism”, Tamara Rice Lave, Jj Prescott, Grady Bridges

Articles

What is the actual rate of sexual recidivism given the well‐ known fact that many crimes go unreported? This is a difficult and important problem, and in “The dark figure of sexual recidivism,” Nicholas Scurich and Richard S. John (2019) attempt to make progress on it by “estimat[ing] actual recidivism rates . . . given observed rates of reoffending” (p. 171). In this article, we show that the math in their probabilistic model is flawed, but more importantly, we demonstrate that their conclusions follow ineluctably from their empirical assumptions and the unrepresentative empirical research they cite to benchmark their calculations. …


What We Think, What We Know And What We Think We Know About False Convictions, Samuel Gross Jan 2017

What We Think, What We Know And What We Think We Know About False Convictions, Samuel Gross

Articles

False convictions are notoriously difficult to study because they can neither be observed when they occur nor identified after the fact by any plausible research strategy. Our best shot is to collect data on those that come to light in legal proceedings that result in the exoneration of the convicted defendants. In May 2012, the National Registry of Exonerations released its first report, covering 873 exonerations from January 1989 through February 2012. By October 15, 2016, we had added 1,027 cases: 599 exonerations since March 1, 2012, and 428 that had already happened when we issued our initial report but …


Racial Disparity In Federal Criminal Sentences, M. Marit Rehavi, Sonja B. Starr Dec 2014

Racial Disparity In Federal Criminal Sentences, M. Marit Rehavi, Sonja B. Starr

Articles

Using rich data linking federal cases from arrest through to sentencing, we find that initial case and defendant characteristics, including arrest offense and criminal history, can explain most of the large raw racial disparity in federal sentences, but significant gaps remain. Across the distribution, blacks receive sentences that are almost 10 percent longer than those of comparable whites arrested for the same crimes. Most of this disparity can be explained by prosecutors’ initial charging decisions, particularly the filing of charges carrying mandatory minimum sentences. Ceteris paribus, the odds of black arrestees facing such a charge are 1.75 times higher than …


Sex Offender Law And The Geography Of Victimization, Amanda Y. Agan, J. J. Prescott Dec 2014

Sex Offender Law And The Geography Of Victimization, Amanda Y. Agan, J. J. Prescott

Articles

Sex offender laws that target recidivism (e.g., community notification and residency restriction regimes) are premised—at least in part—on the idea that sex offender proximity and victimization risk are positively correlated. We examine this relationship by combining past and current address information of registered sex offenders (RSOs) with crime data from Baltimore County, Maryland, to study how crime rates vary across neighborhoods with different concentrations of resident RSOs. Contrary to the assumptions of policymakers and the public, we find that, all else equal, reported sex offense victimization risk is generally (although not uniformly) lower in neighborhoods where more RSOs live. To …


Evidence-Based Sentencing And The Scientific Rationalization Of Discrimination, Sonja B. Starr Jan 2014

Evidence-Based Sentencing And The Scientific Rationalization Of Discrimination, Sonja B. Starr

Articles

This Article critiques, on legal and empirical grounds, the growing trend of basing criminal sentences on actuarial recidivism risk prediction instruments that include demographic and socioeconomic variables. I argue that this practice violates the Equal Protection Clause and is bad policy: an explicit embrace of otherwise- condemned discrimination, sanitized by scientific language. To demonstrate that this practice raises serious constitutional concerns, I comprehensively review the relevant case law, much of which has been ignored by existing literature. To demonstrate that the policy is not justified by countervailing state interests, I review the empirical evidence underlying the instruments. I show that …


Rate Of False Conviction Of Criminal Defendants Who Are Sentenced To Death, Samuel R. Gross, Barbara O'Brien, Chen Hu, Edward H. Kennedy Jan 2014

Rate Of False Conviction Of Criminal Defendants Who Are Sentenced To Death, Samuel R. Gross, Barbara O'Brien, Chen Hu, Edward H. Kennedy

Articles

The rate of erroneous conviction of innocent criminal defendants is often described as not merely unknown but unknowable. There is no systematic method to determine the accuracy of a criminal conviction; if there were, these errors would not occur in the first place. As a result, very few false convictions are ever discovered, and those that are discovered are not representative of the group as a whole. In the United States, however, a high proportion of false convictions that do come to light and produce exonerations are concentrated among the tiny minority of cases in which defendants are sentenced to …


Did Booker Increase Sentencing Disparity? Why The Evidence Is Unpersuasive, Sonja B. Starr Jan 2013

Did Booker Increase Sentencing Disparity? Why The Evidence Is Unpersuasive, Sonja B. Starr

Articles

The Sentencing Commission’s recent report on the effects of United States v.Booker makes a number of very worri- some claims.The most alarming is that the gap in sen- tences between otherwise similar Black and White men has nearly quadrupled: from 4.5 percent before Booker, to 15 percent after it, to 19.5 percent after United States v. Kimbrough and United States v.Gall. 1 The Commission further claims that interjudge disparity has increased in two-thirds of the federal districts, and that interdistrict variation has also increased.2 If its findings were accurate, and if these changes could be causally attributed to Booker and …

Frequency And Predictors Of False Conviction: Why We Know So Little, And New Data On Capital Cases, Samuel R. Gross, Barbara O'Brien Jan 2008

Frequency And Predictors Of False Conviction: Why We Know So Little, And New Data On Capital Cases, Samuel R. Gross, Barbara O'Brien

Articles

In the first part of this article, we address the problems inherent in studying wrongful convictions: our pervasive ignorance and the extreme difficulty of obtaining the data that we need to answer even basic questions. The main reason that we know so little about false convictions is that, by definition, they are hidden from view. As a result, it is nearly impossible to gather reliable data on the characteristics or even the frequency of false convictions. In addition, we have very limited data on criminal investigations and prosecutions in general, so even if we could somehow obtain data on cases …


Exonerations In The United States 1989 Through 2003, Samuel R. Gross, Kriten Jacoby, Daniel J. Matheson, Nicholas Montgomery, Sujata Patil Jan 2005

Exonerations In The United States 1989 Through 2003, Samuel R. Gross, Kriten Jacoby, Daniel J. Matheson, Nicholas Montgomery, Sujata Patil

Articles

On August 14, 1989, the Cook County Circuit Court in Chicago, Illinois, vacated Gary Dotson's 1979 rape conviction and dismissed the charges.1 Mr. Dotson-who had spent ten years in and out of prison and on parole for this conviction-was not the first innocent prisoner to be exonerated and released in America. But his case was a breakthrough nonetheless: he was the first who was cleared by DNA identification technology. It was the beginning of a revolution in the American criminal justice system. Until then, exonerations of falsely convicted defendants were seen as aberrational. Since 1989, these once-rare events have become …


Road Work: Racial Profiling And Drug Interdiction On The Highway, Samuel R. Gross, Katherine Y. Bames Jan 2002

Road Work: Racial Profiling And Drug Interdiction On The Highway, Samuel R. Gross, Katherine Y. Bames

Articles

Hypocrisy about race is hardly new in America, but the content changes. Recently the spotlight has been on racial profiling. The story of Colonel Carl Williams of the New Jersey State Police is a wellknown example. On Sunday, February 28, 1999, the Newark Star Ledger published a lengthy interview with Williams in which he talked about race and drugs: "Today... the drug problem is cocaine or marijuana. It is most likely a minority group that's involved with that."4 Williams condemned racial profiling - "As far as racial profiling is concerned, that is absolutely not right. It never has been con-doned …


Hardening Of The Attitudes: Americans' Views On The Death Penalty, Phoebe C. Ellsworth, Samuel R. Gross Jan 1994

Hardening Of The Attitudes: Americans' Views On The Death Penalty, Phoebe C. Ellsworth, Samuel R. Gross

Articles

American support for the death penalty has steadily increased since 1966, when opponents outnumbered supporters, and now in the mid-1990s is at a near record high. Research over the last 20 years has tended to confirm the hypothesis that most people’s death penalty attitudes (pro or con) are based on emotion rather than information or rational argument. People feel strongly about the death penalty, know little about it, and feel no need to know more. Factual information (e.g., about deterrence and discrimination) is generally irrelevant to people’s attitudes, and they are aware that this is so. Support for the death …


How To Use, Abuse—And Fight Back With—Crime Statistics, Yale Kamisar Jan 1972

How To Use, Abuse—And Fight Back With—Crime Statistics, Yale Kamisar

Articles

Statistics have an almost magical appeal in a "fact"-minded culture such as ours, among a people conditioned and accustomed to watch for-and attach great significance to-even the smallest fluctuations in say, the unemployment rate. Hence, as Darrell Huff graphically demonstrated in his famous little book, How to Lie with Statistics (1954), they can be-and have been-manipulated to terrorize or calm, inflate or depreciate, and above all, to sensationalize and over simplify. As Harvard criminologist Lloyd Ohlin noted recently, statistics are especially potent when "they give a sense of solid reality (usually false) to something people vaguely apprehend and when they …
