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.

May an Officer Assume a False Identity Online in Order to “Friend” a Suspect?

Officers are allowed to misrepresent their identities in the course of their investigations: they may pose as drug buyers, or prostitutes, or members of an organized crime syndicate. Is the same thing true online? In other words, may an officer claim to be someone else in order to “friend” a suspect on social media and thereby gain access to whatever information the suspect has posted? The answer isn’t clear yet, but I would guess that courts ultimately will say yes.

Warrant Required for Testing of Unconscious DWI Suspect

The United States Supreme Court heard oral arguments this morning in three cases involving the chemical testing of impaired drivers. The question before the court in each case is whether, in the absence of a warrant, a state may make it a crime for a person to refuse to take a chemical test to detect the presence of alcohol in the person’s blood. I’m eager to hear what the high court has to say about this issue and to learn whether it will impact North Carolina’s implied consent laws, which, like the laws in every other state, do provide for warrantless chemical testing, but which do not criminalize refusal to be tested. But we don’t have to wait for the Supreme Court’s opinion to see how our state’s implied consent laws are evolving in a post-Missouri v. McNeely world. The North Carolina Court of Appeals decided a significant case yesterday, ruling in State v. Romano, __ N.C. App. ___ (2016), that the warrantless withdrawal of blood from an unconscious impaired driving suspect violated the Fourth Amendment, notwithstanding a state statute that permits such actions.

North Carolina Supreme Court Affirms Post-Rodriguez Court of Appeals Ruling in State v. Warren

Last April, 2015, the United States Supreme Court in Rodriguez v. United States, 135 S. Ct. 1609 (2015), significantly limited the scope of a traffic stop. The Court ruled that an officer may not extend a completed traffic stop for any period of time, no matter how brief, to conduct a dog sniff—absent reasonable suspicion of criminal activity (or consent). The Court rejected the government’s argument that an officer may incrementally prolong a traffic stop, which some lower courts, including North Carolina’s, had justified as a de minimis intrusion. The Court reasoned that a dog alert is not a permissible part of a traffic stop because it detects evidence of ordinary criminal wrongdoing, which is not part of an officer’s traffic mission. The Court, however, clearly indicated that if a dog sniff or other non-traffic-related activity does not add any time to the stop (in this case, it added 7–8 minutes), then the dog sniff or other activity is valid under the Fourth Amendment, as it previously had ruled in Illinois v. Caballes, 543 U.S. 405 (2005).

Do DWI Suspects Have a Right to the Least Intrusive Chemical Test?

In its seminal opinion establishing the State’s right to withdraw blood from a DWI suspect over his objection and without a warrant when there are exigent circumstances, the United States Supreme Court left a significant question unanswered. The court in Schmerber v. California, 384 U.S. 747 (1966), noted that the petitioner “is not one of the few who on grounds of fear, concern for health, or religious scruple might prefer some other means of testing, such as the ‘Breathalyzer’ test petitioner refused. . . . We need not decide whether such wishes would have to be respected.” Id. at 771.

So how have courts in the ensuing four decades answered this question? Must an impaired driving suspect be offered the least intrusive type of chemical test available or a choice about the type of testing when he or she has a sincere objection to a particular test?

 

Body Cameras and the Mosaic Theory of the Fourth Amendment

Many law enforcement officers, including those in five of North Carolina’s six largest cities, are or soon will be wearing body cameras. The prevailing view is that the use of such cameras doesn’t constitute a Fourth Amendment search because the cameras record only what an officer is already able to see. This post considers whether the increasing adoption of body cameras and other data-collection technologies could eventually result in body camera recordings being considered searches under the so-called mosaic theory of the Fourth Amendment.
