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

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:

United States Supreme Court Clarifies When Consent to Search by One Residential Occupant Is Valid When a Co-Occupant Has Previously Objected
Last week the United States Supreme Court in Fernandez v. California (February 25, 2014) clarified an issue left open in its ruling in Georgia v.

Heavy Traffic to a Residence and Probable Cause
The court of appeals decided a case today concerning a fact pattern that arises frequently in drug cases. State v.

Video Surveillance Cameras
Law enforcement officers are making more and more use of video surveillance cameras, often mounted on utility poles. Sometimes these cameras are focused on streets or parks, as discussed in this Fayetteville Observer article. Sometimes they are focused on suspects’ residences.
