Jeff Welty wrote a post in 2010 on when a seizure occurs after an officer operates emergency lights to order a driver to stop his or her vehicle. This post updates his post by summarizing the relatively recent North Carolina Court of Appeals case of State v. Mangum, ___ N.C. App. ___, 795 S.E.2d 106 (Dec. 6, 2016), review denied, ___ N.C. ___, 2017 WL 1086917 (March 16, 2017), which ruled on this issue and provides a useful summary of the case law in North Carolina and other jurisdictions.

How’s a Magistrate to Know Whether a Confidential Informant Is Reliable?
Search warrant applications are often based on information from confidential informants. Whether the informant is reliable is critical. Information from a reliable informant is often sufficient to establish probable cause, while information from an informant whose reliability isn’t established is often insufficient. So how’s a magistrate to know whether an informant is reliable? A recent opinion from the court of appeals provides an opportunity to examine that question.
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.]

Body-Camera Footage Leads to Plain Error Reversal in State v. Miller
My colleagues here have previously blogged about the impact of Rodriguez v. United States, 575 U.S. ___, 135 S. Ct. 1609 (2015), and my predecessor Alyson Grine created a handy chart summarizing North Carolina cases on the matter, found here. Rodriguez of course held that a traffic stop may not be extended beyond the time necessary to accomplish the purpose of the stop, absent reasonable suspicion or consent, and effectively overruled prior case law in NC allowing de minimis extensions of such stops. In December, the Court of Appeals issued a new, unanimous decision applying this rule in State v. Miller, ___ N.C. App. ____ (Dec. 20, 2016), temp. stay allowed, ___ N.C. ___ (Jan. 4, 2017). I found it noteworthy for the role that the officer’s body-camera footage played, as well as for the fact that the court applied plain error review to grant the defendant a new trial.
North Carolina Supreme Court Upholds Search of Vehicle Located on Premises as Within Scope of Search Warrant
The North Carolina Supreme Court in State v. Lowe (December 21, 2016) ruled that a search warrant validly authorized a search of a vehicle parked on the driveway of the premises and within its curtilage, and it reversed a contrary ruling by the Court of Appeals (State v. Lowe, 774 S.E.2d 893, 21 July 2015). This post discusses the supreme court’s ruling.

Drug Users, Drug Sellers, and Probable Cause
Here’s a common fact pattern: Officers find a person in possession of drugs. The officers say, in effect, “we won’t arrest you if you’ll tell us who sold you the drugs.” The person then reports having recently purchased the drugs from a particular person at that person’s home. Does this provide probable cause to support a search warrant for the supplier’s home?
What Constitutes Valid Consent When One Co-Occupant Consents and the Other Co-Occupant Does Not?
Generally, officers may obtain a valid consent to search only from a person whose reasonable expectation of privacy may be invaded by the proposed search. Sometimes two or more people—for example, spouses or roommates—share a reasonable expectation of privacy in the same place. Generally, either person may give valid consent to an officer. United States v. Matlock, 415 U.S. 164 (1974) (common authority over premises found). However, as discussed below, an exception to this general rule may exist when a physically-present occupant objects.
Probable Cause and Search Warrants for Cell Phones
Law enforcement officers often seek search warrants for suspects’ cell phones. When they do, judicial officials must determine what sort of evidence is needed to support the issuance of a warrant. Many people have their phones with them at all times, and use their phones to document and discuss every aspect of their daily activities. Does that mean that when an officer has probable cause to believe that a suspect committed a crime, the officer automatically has probable cause to search the suspect’s cell phone for evidence of the crime? Or does the officer need a more specific nexus between the crime and the phone?
Ordering Occupants Out of Their Vehicles — And into Officers’ Cruisers
May an officer, during a traffic stop, order an occupant out of the stopped vehicle? Into the officer’s vehicle? The law on this question has become unsettled.
