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 …

This is an essay on Professor Sarah A. Seo’s new book, Policing the Open Road: How Cars Transformed American Freedom (Harvard Univ. Press 2019). I focus on Professor Seo’s analysis of Carroll v. United States, 267 U.S. 132 (1925) and Brinegar v. United States, 338 U.S. 160 (1949). Carroll is important not only because it was the Court’s first car case. Understanding Carroll (and Brinegar, which solidified and expanded Carroll’s holding) is essential because, nearly one hundred years later, its logic continues to direct how the modern Court resolves Fourth Amendment claims of motorists. Put simply, a majority of today’s …

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 …

Then the police officer told the suspect, without just cause, "I bet you are hiding [drugs] under your balls. If you have drugs under your balls, I am going to fuck your balls up."
Jon Gould and Stephen Mastrofski document astonishingly high rates of unconstitutional police searches in their groundbreaking article, "Suspect Searches: Assessing Police Behavior Under the U.S. Constitution." By their conservative estimate, 30% of the 115 police searches they studied – searches that were conducted by officers in a department ranked in the top 20% nationwide, that were systematically observed by trained field observers, and that were coded …
