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 …

Ending Cps Home Searches' Evasion Of The Fourth Amendment, Joshua Gupta-Kagan

Faculty Scholarship

Every year, Child Protective Service (CPS) agencies investigate about 3 million families around the country for alleged neglect or abuse of their children. Under agency policies, all of those millions of investigations include searches of families’ homes. CPS investigators knock on the door (usually unannounced), look in every room of the house, open kitchen cabinets, sometimes inspect children’s bodies, and generally look for any evidence of child maltreatment. Yet CPS agencies rarely seek a warrant, and typically act as if that is unnecessary. (P. 18 & n.86.)

Following The Script: Narratives Of Suspicion In Terry Stops In Street Policing, Jeffery Fagan, Amanda Geller

Faculty Scholarship

Regulation of Terry stops of pedestrians by police requires articulation of the reasonable and individualized bases of suspicion that motivate their actions. Nearly five decades after Terry, courts have found it difficult to articulate the boundaries or parameters of reasonable suspicion. The behavior and appearances of individuals combine with the social and spatial contexts in which police observe them to create an algebra of suspicion. Police can proceed to approach and temporarily detain a person at a threshold of suspicion that courts have been unable and perhaps unwilling to articulate. The result has been sharp tensions within Fourth Amendment …

Randomization And The Fourth Amendment, Bernard Harcourt, Tracey L. Meares

Faculty Scholarship

Randomized checkpoint searches are generally taken to be the exact antithesis of reasonableness under the Fourth Amendment. In the eyes of most jurists checkpoint searches violate the central requirement of valid Fourth Amendment searches – namely, individualized suspicion. We disagree. In this Article, we contend that randomized searches should serve as the very lodestar of a reasonable search. The notion of "individualized" suspicion is misleading; most suspicion in the modem policing context is group based and not individual specific. Randomized searches by definition are accompanied by a certain level of suspicion. The constitutional issue, we maintain, should not turn on …

Why Not A Miranda For Searches?, Gerard E. Lynch

Faculty Scholarship

I am delighted to be here today.

I am delighted to be at The Ohio State University, which has not only built a truly extraordinary criminal law and procedure faculty, including Professor Joshua Dressler, Alan Michaels, Sharon Davies, and Douglas Berman, but has also accumulated a large number of alumni of my home institution, Columbia Law School, including my former students, Professor Edward Foley and the aforesaid Professors Davies and Michaels, as well as Professor Deborah Jones Merritt, who is quite literally a daughter of Columbia, where her father is a distinguished emeritus member of the faculty, my esteemed senior …

Unconstitutional Police Searches And Collective Responsibility, Bernard E. Harcourt

Faculty Scholarship

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 …

Reappraising T.L.O.'S Special Needs Doctrine In An Era Of School-Law Enforcement Entanglement, Joshua Gupta-Kagan

Faculty Scholarship

This essay presents one doctrinal method for lawyers to defend children accused of criminal charges in juvenile or adult court: attacking the applicability of the nearly twenty-year old case, New Jersey v. T.L.O. to most school searches. T.L.O. established a lower standard for searches of students by school officials, but it explicitly did not decide what standard the government must meet to justify school searches performed by police officers, creating a doctrinal starting point for advocates to raise challenges to searches involving police. More fundamentally, the T.L.O. Court based its decision on the presumption that firm gates separate public school …

Police, Community Caretaking, And The Fourth Amendment, Debra A. Livingston

Faculty Scholarship

The local police have multiple responsibilities, only one of which is the enforcement of criminal law. Police gather eyewitness accounts in the aftermath of a shooting, but they also assist lost children in locating their parents. Police identify and arrest those who have committed felonies, but they also respond to heart attack victims and help inebriates find their way home. Sometimes police check on the well-being of elderly citizens. As Professor Goldstein said some twenty years ago, "The total range of police responsibilities is extraordinarily broad .... Anyone attempting to construct a workable definition of the police role will typically …

Search And Seizure Of The Media: A Statutory, Fourth Amendment And First Amendment Analysis, James S. Liebman

Faculty Scholarship

On the evening of October 10, 1974, police appeared at radio station KPFK-FM in Los Angeles with a warrant authorizing them to search the premises for a New World Liberation Front (NWLF) "communique" that took credit for a recent bombing. The officers conducted an intensive 8-hour search-combing files, listening to tapes, and looking through reporters' notes – finally concluding that the NWLF letter was not at the station. The KPFK search warrant was one of six that California law enforcement officials have executed at press offices since 1972. The circumstances surrounding the incident illustrate the rationale behind the recent development …
