United States v. William Davis, Jr.

Plain English (For Everyone)

Police searched a man's cell phone after arresting him without a warrant. The court ruled this was allowed because the data on the phone could have been lost or deleted quickly. This means evidence found on the phone can be used against him in court.

For Legal Practitioners

The Fourth Circuit affirmed the denial of a motion to suppress, holding that the warrantless search of a cell phone incident to arrest was justified by exigent circumstances. The court reasoned that the imminent risk of data destruction (e.g., battery depletion, remote wiping) created a sufficient exigency to bypass the warrant requirement.
