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.

North Carolina Court of Appeals Issues Ruling on a Strip Search by Law Enforcement Officers
In 2013, I wrote two posts on strip searches by law enforcement officers, which are available here and here. This post discusses the first published North Carolina appellate court strip search case since these posts: State v. Collins, 2016 WL 385690 (N.C. App., Feb. 2, 2016).
State v. Perry, Cell Site Location Information, and the Exclusionary Rule
Last week, the court of appeals decided State v. Perry. It’s the appellate division’s first foray into cell site location information and a case that raises questions about the status of the exclusionary rule in North Carolina.
Updated Traffic Stops Paper Now Available
I’ve updated my paper on traffic stops to include Rodriguez v. United States, __ U.S. __, 135 S. Ct. 1609 (2015), and other recent cases. It’s available here. For those not familiar with the paper, it is a summary of the law regarding traffic stops, including typical reasons for such stops, the stops’ duration, the techniques … Read more
Can a Magistrate Issue a Search Warrant for a Computer or a Cell Phone?
I’ve had the same question several times recently: can a magistrate issue a search warrant for a computer or a cell phone? The answer is yes. This post explains why that’s so, and why there’s some confusion about the issue.
The Early Impact of Rodriguez v. United States
About three months ago, the United States Supreme Court decided Rodriguez v. United States, __ U.S. __, 135 S. Ct. 1609 (2015). I wrote about it here. In a nutshell, the Court ruled that once the purpose of a traffic stop has been addressed – or reasonably should have been addressed – an officer can’t extend the stop, even briefly, for unrelated investigative activities such as drug dog sniffs, unless the officer has reasonable suspicion of criminal activity to support the continued detention.
The rule is clear enough in theory but it can give rise to some difficult questions in practice. May an officer engage in brief chit-chat with a motorist, or does such interaction constitute an extension of the stop? What about inquiring about a motorist’s travel plans, or a passenger’s, where such inquiries may bear on the likelihood of driver fatigue but also may be used to seek out inconsistencies that may be evidence of illicit activity? May an officer comply with Rodriguez by multi-tasking, i.e., by asking unrelated questions while examining a driver’s license, or does multi-tasking inherently slow an officer down and so extend a stop?
Courts across the country are beginning to address some of these questions. This post summarizes the early impact of Rodriguez.
State v. Williford: Gumshoes, Trash, Parking Lots and DNA
Kathy Taft was bludgeoned and raped on March 5, 2010, as she lay in the bedroom of a friends’ home in Raleigh recovering from surgery. She died four days later. Raleigh police tracked down her killer, Jason Williford, through what then-police chief Harry Dolan called “gumshoe detective work”: They collected and tested trash discarded by neighborhood men who refused to provide samples of their DNA.
Updated Paper on Traffic Stops
I’ve recently updated my paper on traffic stops. As before, it covers stops from start to finish, including the legal standard for making a stop, the length of a stop, and investigative techniques that may be used during a stop. I may need to update it again after the Supreme Court decides United States v. … Read more
Warrantless Stops 101 — Was the Stop Supported by Reasonable Suspicion?
In my first Warrantless Stops 101 post, I offered these basic questions to frame the analysis:
- Did a seizure occur?
- If so and it was a stop, was it supported by reasonable suspicion or other valid basis?
- If reasonable suspicion supported the stop, was the officer’s subsequent conduct sufficiently limited in scope?
- If the seizure was an arrest, was it supported by probable cause?
- If the arrest was supported by probable cause, was the search permissible?
My first post focused on whether a seizure occurred. This one looks at whether the stop was supported by reasonable suspicion. If so, the stop itself is constitutional and the only remaining issue is whether the officer’s conduct exceeded the scope of the stop, a topic I’ll take up in a later post.
Article for Officers and Others on Search Warrants for Digital Devices
Years ago, the School of Government did quite a bit of training for the Highway Patrol and other law enforcement officers. These days, we focus most of our criminal law courses on judges, lawyers, and magistrates. But I still view officers as an important audience for our work, and I recently wrote an article for Police Chief magazine that is meant to help officers obtain valid search warrants for digital devices.
