Is the Exigent Circumstances Doctrine an Exception to the Warrant Requirement, or Something More?


I have long thought of the exigent circumstances doctrine as an exception to the warrant requirement – it allows a search to be conducted when probable cause is present but it is impractical for officers to take the time to obtain a search warrant. That understanding was shaken when I read Phil Dixon’s summary of United States v. Curry, 937 F.3d 363 (4th Cir. 2019). The majority in Curry ruled that exigent circumstances allowed officers to search several men without probable cause or even reasonable suspicion because they were walking away from an area where shots had just been fired. In other words, the court took the position that exigent circumstances excused not only the lack of a warrant, but also the lack of individualized suspicion. Have I been mistaken all these years?

May an Officer Run a Motorist’s Criminal Record During a Traffic Stop?

An officer who stops a motorist for a traffic infraction may run a computer check on the driver’s license and may check for outstanding warrants. The results of these checks may determine how the officer proceeds. For example, if a check reveals that the driver’s license is revoked, the officer may charge the driver with DWLR and may direct the driver that he or she cannot drive the vehicle away from the location of the stop.

May an officer also check a motorist’s criminal record? Such historical information is less likely to dictate the officer’s course of action. But knowing whether a motorist has a record of violent crimes may help an officer determine how cautious he or she must be while completing the stop. This post discusses whether an officer may take time to run a motorist’s criminal record, and summarizes two recent cases on point.

Fourth Circuit Sets Out Authority to Frisk When a State’s Law Permits Possession of Concealed Firearm

The Fourth Circuit Court of Appeals, on a rehearing of a case en banc, held in United States v. Robinson, 2017 WL 280727 (Jan. 23, 2017), that an officer had the authority to conduct a frisk of a lawfully-stopped person whom the officer reasonably believed to be armed with a concealed firearm, regardless of whether the person may have been legally entitled to carry the firearm. This post discusses the ruling and its possible influence in the development of the law of frisk in North Carolina state courts. [For those who received my summary of this case as a subscriber to the criminal law listserv, this is the same summary but with the addition of an analysis and comment section at the end of this post.]

The United States Court of Appeals for the Fourth Circuit issued its opinion in Doe v. Cooper yesterday. A unanimous panel of the court affirmed a decision from Middle District of North Carolina finding two parts of G.S. 14-208.18—North Carolina’s premises restrictions for certain sex offenders—unconstitutional.

Vinson, Voisine, and Misdemeanor Crimes of Domestic Violence

The United States Supreme Court recently decided a case about what counts as a “misdemeanor crime of domestic violence” for purposes of the federal statute prohibiting individuals who have been convicted of such crimes from possessing firearms. I’ve had several questions about whether the ruling affects last year’s Fourth Circuit decision holding that North Carolina assaults generally don’t qualify as “misdemeanor crime[s] of domestic violence.” For the reasons set out below, I don’t think the Supreme Court case clearly overrules the Fourth Circuit’s decision.

Fourth Circuit Reverses Graham: No Warrant Required for Historical Cell Site Location Information

Last year, a panel of the Fourth Circuit decided United States v. Graham, 796 F.3d 332 (4th Cir. 2015). The panel ruled that “the government conducts a search under the Fourth Amendment when it obtains and inspects a cell phone user’s historical [cell site location information (CSLI)] for an extended period of time. . . . Its inspection by the government, therefore, requires a warrant, unless an established exception to the warrant requirement applies.” I discussed Graham here and here. Last week, the en banc Fourth Circuit reversed the panel, ruling that under the third-party doctrine, a cell phone subscriber has no reasonable expectation of privacy in historical cell site location information that he or she shares with a service provider, so it isn’t a Fourth Amendment “search” when law enforcement obtains such information, and a warrant isn’t required. The en banc opinion is here. This post discusses the opinion and considers the possibility of Supreme Court review or action by Congress.
