Are Police Officers Bayesians? Police Updating In Investigative Stops, Jeffrey A. Fagan, Lila J.E. Nojima

Faculty Scholarship

Theories of rational behavior assume that actors make decisions where the benefits of their acts exceed their costs or losses. If those expected costs and benefits change over time, behavior will change accordingly as actors learn and internalize the parameters of success and failure. In the context of proactive policing, police stops that achieve any of several goals — constitutional compliance, stops that lead to “good” arrests or summonses, stops that lead to seizures of weapons, drugs, or other contraband, or stops that produce good will and citizen cooperation — should signal to officers the features of a stop that …

Terry'S Original Sin, Jeffrey Fagan

Faculty Scholarship

In Mapp v. Ohio, the U.S. Supreme Court extended the due process protections of the exclusionary rule to include all "constitutionally unreasonable searches" that were done without a basis of probable cause. In the seven years after Mapp, when homicide rates in the U.S. nearly doubled, riots broke out in at least forty-seven U.S. cities. During the same era, a heroin epidemic gripped the nation's urban centers, giving rise to street drug markets and associated violence and pressures on law enforcement to curb those markets. As violence increased, a turn in the nation's political culture questioned Mapp's restraints on …

Stop Terry : Reasonable Suspicion, Race, And A Proposal To Limit Terry Stops, Renée M. Hutchins

Faculty Scholarship

The Terry doctrine, which grants a police officer the authority to stop and frisk based on his or her reasonable suspicion rather than probable cause, was created by the Supreme Court at a time when the nation con- fronted a particular moment of violent racial strife. Since Terry was decided, the Supreme Court has continued to expand the reach of the doctrine—which opened the door for potential abuse. Existing data is increasingly proving that the loosening of constitutional standards is causing substantial harms to people of color nationwide. This article joins the existing scholarly discussion surrounding this decision to suggest …

Framing The Fourth, Tracey Maclin

Faculty Scholarship

History is again an important element of the Supreme Court’s Fourth Amendment analysis. In Wyoming v. Houghton, Justice Scalia’s opinion for the Court announced that a historical inquiry is the starting point for every Fourth Amendment case. William Cuddihy’s book on the origins and original meaning of the Fourth Amendment will undoubtedly assist the Justices (and everyone else) in understanding the history of search and seizure law.

Cuddihy’s historical analysis is unprecedented. As Justice O’Connor has described it, Cuddihy’s work is “one of the most exhaustive analyses of the original meaning of the Fourth Amendment ever undertaken.” Cuddihy reviewed thousands …

Privacy And The Criminal Arrestee Or Suspect: In Search Of A Right, In Need Of A Rule, Sadiq Reza

Faculty Scholarship

Criminal accusation stigmatizes. Merely having been accused of a crime lasts in the public eye, damaging one's reputation and threatening current and future employment, relationships, social status, and more. But vast numbers of criminal cases are dismissed soon after arrest, and countless accusations are unfounded or unprovable. Nevertheless, police officers and prosecutors routinely name criminal accusees to the public upon arrest or suspicion, with no obligation to publicize a defendant's exoneration, or the dismissal of his case, or a decision not to file charges against him at all. Other individuals caught up in the criminal process enjoy protections against the …
