Catchall Policing And The Fourth Amendment, Nirej Sekhon

Duke Law Journal Online

American police do a bit of everything. They direct traffic, resolve private disputes, help the sick and injured, and do animal control. Far less frequently than one might think, they make arrests. Americans reflexively call the police for troubles, big and small. The “catchall tradition” is shorthand for this melding of non-adversarial, public assistance with adversarial, crime-control functions. The catchall tradition means that civilians are exposed to the police’s coercive power as a condition of receiving police help. This Article contends that the catchall tradition is antithetical to constitutional police regulation. The Supreme Court has distinguished adversarial from non-adversarial state …

The End Of Intuition-Based High-Crime Areas, Ben Grunwald, Jeffrey Fagan

Faculty Scholarship

In 2000, the Supreme Court held in Illinois v. Wardlow that a suspect’s presence in a “high-crime area” is relevant in determining whether an officer has reasonable suspicion to conduct an investigative stop. Despite the importance of the decision, the Court provided no guidance about what that standard means, and over fifteen years later, we still have no idea how police officers understand and apply it in practice. This Article conducts the first empirical analysis of Wardlow by examining data on over two million investigative stops conducted by the New York Police Department from 2007 to 2012.

Dna And Distrust, Kerry Abrams, Brandon L. Garrett

Faculty Scholarship

Over the past three decades, government regulation and funding of DNA testing has reshaped the use of genetic evidence across various fields, including criminal law, family law, and employment law. Courts have struggled with questions of when and whether to treat genetic evidence as implicating individual rights, policy trade-offs, or federalism problems. We identify two modes of genetic testing: identification testing, used to establish a person’s identity, and predictive testing, which seeks to predict outcomes for a person. Judges and lawmakers have often drawn a bright line at predictive testing, while allowing uninhibited identity testing. The U.S. Supreme Court in …

In The Absence Of Scrutiny: Narratives Of Probable Cause, Mitu Gulati, Jack Knight, David F. Levi

Faculty Scholarship

This Article reports on a set of roughly thirty interviews with federal magistrate judges. The focus of the interviews was the impact of the Supreme Court case, United States v. Leon, on the behavior of magistrate judges. Leon, famously, put in place the "good faith" exception for faulty warrants that were obtained by the officers in good faith. The insertion of this exception diminished significantly the incentive for defendants to challenge problematic warrant grants. That effect, in turn, could have diminished the incentive for magistrate judge scrutiny of the warrants at the front end of the process. We do not …

Biometric Id Cybersurveillance, Margaret Hu

Faculty Scholarship

The implementation of a universal digitalized biometric ID system risks normalizing and integrating mass cybersurveillance into the daily lives of ordinary citizens. ID documents such as driver’s licenses in some states and all U.S. passports are now implanted with radio frequency identification (RFID) technology. In recent proposals, Congress has considered implementing a digitalized biometric identification card—such as a biometric-based, “high-tech” Social Security Card—which may eventually lead to the development of a universal multimodal biometric database (e.g., the collection of the digital photos, fingerprints, iris scans, and/or DNA of all citizens and noncitizens). Such “hightech” IDs, once merged with GPS-RFID tracking …

Searching Secrets, Nita A. Farahany

Faculty Scholarship

A Fourth Amendment violation has traditionally involved a physical intrusion such as the search of a house or the seizure of a person or her papers. Today, investigators rarely need to break down doors, rummage through drawers, or invade one’s peace and repose to obtain incriminating evidence in an investigation. Instead, the government may unobtrusively intercept information from electronic files, GPS transmissions, and intangible communications. In the near future, it may even be possible to intercept information directly from suspects’ brains. Courts and scholars have analogized modern searches for information to searches of tangible property like containers and have treated …

The Ice Storm In U.S. Homes: An Urgent Call For Policy Change, Katherine Evans

Faculty Scholarship

Since its creation in 2003, the Bureau of Immigration and Customs Enforcement (ICE) has used increasingly aggressive tactics to enforce U.S. immigration law. One of ICE's most prominent enforcement initiatives is its practice of raiding the homes of immigrants. Accounts of home raids from victims all over the country reveal a pattern of practice that differs widely from ICE's official statements regarding raids. This paper establishes that although immigration officials are governed by the Fourth Amendment when conducting home raids, ICE's agents nonetheless regularly violate the Constitution when carrying out home raids. Additionally, this paper argues that the number and …

Fourth Amendment Accommodations: (Un)Compelling Public Needs, Balancing Acts, And The Fiction Of Consent, Guy-Uriel Charles

Faculty Scholarship

The problems of public housing-including crime, drugs, and gun violence- have received an enormous amount of national attention. Much attention has also focused on warrantless searches and consent searches as solutions to these problems. This Note addresses the constitutionality of these proposals and asserts that if the Supreme Court's current Fourth Amendment jurisprudence is taken to its logical extremes, warrantless searches in public housing can be found constitutional. The author argues, however, that such an interpretation fails to strike the proper balance between public need and privacy in the public housing context. The Note concludes by proposing alternative consent-based regimes …
