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.

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:

  1. Did a seizure occur?
  2. If so and it was a stop, was it supported by reasonable suspicion or other valid basis?
  3. If reasonable suspicion supported the stop, was the officer’s subsequent conduct sufficiently limited in scope?
  4. If the seizure was an arrest, was it supported by probable cause?
  5. 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.

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:

  1. Did a seizure occur?
  2. If so and it was a stop, was it supported by reasonable suspicion or other valid basis?
  3. If reasonable suspicion supported the stop, was the officer’s subsequent conduct sufficiently limited in scope?
  4. If the seizure was an arrest, was it supported by probable cause?
  5. If the arrest was supported by probable cause, was the search permissible

This flowchart illustrates the analysis:

State v. Jackson and Pedestrian Evasion

The court of appeals recently decided a case about when a pedestrian’s efforts to avoid an officer provide reasonable suspicion for an investigative stop. The type of encounter involved is reasonably common and the case features a dissent, so it’s worth exploring. The facts. The case is State v. Jackson, and it arose at 9:00 … Read more
