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.
Search and Seizure

Hospitalization of DWI Suspect Does Not Create Per Se Exigency Justifying Warrantless Blood Draw
The Chatham County sheriff’s deputy who arrested Ronald McCrary in Siler City for impaired driving at 7:34 p.m. on December 28, 2010 decided that if McCrary was taken to the hospital, he would obtain a sample of his blood without a warrant. McCrary was in fact taken to a nearby hospital—at his insistence—where he refused to cooperate with the medical staff and refused to consent to the withdrawal of his blood. Once the hospital discharged McCrary at 9:13 p.m., several officers restrained him while hospital staff withdrew his blood. Was the blood draw legal?
Police Jurisdiction in Satellite and Related Areas
I’ve had several questions recently about the territorial jurisdiction of municipal police in areas outside city limits. This post sums up the law.

Implied Consent Laws Can’t Provide End-Run around McNeely
The United States Supreme Court held in Missouri v. McNeely, 133 S. Ct. 1552 (2013), that the natural dissipation of alcohol in the bloodstream does not constitute an exigency in every impaired driving case that justifies a warrantless, nonconsensual blood draw. In so holding, the court rejected the state’s call for a categorical rule—based solely on the evanescent nature of alcohol—that would authorize warrantless blood draws over a defendant’s objection whenever an officer has probable cause to believe the defendant has been driving while impaired. Some states have continued to argue, however, that nonconsensual warrantless blood draws in impaired driving cases are categorically permissible based on implied consent laws enacted by their state legislatures. Two state supreme courts recently rejected such arguments, holding that implied consent statutes in Nevada and Idaho that do not allow a driver to withdraw consent to testing are unconstitutional. That reasoning might be applied to invalidate the provision of North Carolina’s implied consent law that categorically allows the warrantless testing of unconscious drivers.
Ebola, Quarantines, and Criminal Law
Ebola’s been in the news lately, with several infected individuals on American soil. New York and New Jersey have begun to quarantine individuals arriving from West Africa who have had contact with infected people, and a nurse subjected to quarantine threatened a legal challenge. So, what’s the law? And what are the potential criminal law implications?
Stingrays
This weekend, the Charlotte Observer ran this article, entitled Charlotte Police Investigators Secretly Track Cellphones. The article concerns the use of so-called stingrays, also known as IMSI catchers or cell site simulators. They are machines that simulate cell towers and connect with the cellular telephones located nearby. Officers frequently use them to triangulate the location of a suspect – or more precisely, the location of a suspect’s phone. There’s a controversy about the legal status of these devices, which I’ll summarize in this post.

Warrantless Stops 101: Did a Seizure Occur?
Sorting out Fourth Amendment issues in the context of warrantless stops can be tricky. I like to break the case down into five basic questions:
- 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
This flowchart illustrates the analysis:
New Cumulative Supplement to Arrest, Search, and Investigation in North Carolina and Recent Cases Since Its Publication
The 2014 Cumulative Supplement to Arrest, Search, and Investigation in North Carolina (4th ed. 2011) is now available. It is called a cumulative supplement because it includes the material in the 2013 supplement so you only need the book and the 2014 cumulative supplement to be current. You may order it online here or contact the School of Government Bookstore Manager at 919.966.4120. Continue reading for additional details.
Is Apple Intentionally Crippling Law Enforcement Access to Digital Evidence?
Apple recently announced new iPhones and a new operating system for its mobile devices. Amidst the hubbub, Apple also revealed that the new operating system would render it impossible for Apple to give law enforcement officers access to locked iPhones, even with a search warrant. Many in law enforcement aren’t happy about this, with FBI Director James Comey stating that he can’t understand why companies would “market something expressly to allow people to place themselves beyond the law.” But is that what’s going on?

The Old Portable Breath Test Ain’t What She Used to Be
Portable breath tests don’t go very far anymore in proving whether a suspect is impaired from alcohol. That’s because the legislature amended G.S. 20-16.3(d) in 2006 to provide that the alcohol concentration results from such a test, termed an alcohol screening test by statute, are not admissible in court— not even for purposes of determining … Read more
