Tenth Circuit – United States v. Williams
A Passenger’s Association Alone Does Not Justify a Search
Mar. 17, 2026
-
During a traffic stop, officers encountered a driver with outstanding warrants and documented gang affiliations. His passenger, a cooperative girlfriend with no criminal history, remained at the scene. After arresting the driver, officers detained the passenger and conducted a protective sweep of the vehicle, during which they discovered a firearm.
The Tenth Circuit held that this search violated the Fourth Amendment. The officers lacked specific, articulable facts suggesting the passenger herself was armed and dangerous, and her mere association with the driver was insufficient to justify the search.
-
Reasonable suspicion must be grounded in individualized facts about the person searched, not simply their relationship to a suspected offender.
Fifth Circuit – United States v. Garcia
BOLO Alerts Can Justify Stops (If Done Right)
March 16, 2026
-
Following a shots-fired incident, officers issued a BOLO containing a detailed vehicle description and supporting information. Officers later located a vehicle matching that description and conducted a traffic stop.
The court upheld the stop as lawful.
-
A BOLO can justify a stop when it is sufficiently specific, detailed, and clearly tied to suspected criminal activity.
Fifth Circuit – United States v. Porter
License Plate Readers Are Not a Fourth Amendment Search
Mar. 17, 2026
-
An officer used a license plate reader to identify the vehicle of a wanted suspect, prompting a traffic stop that resulted in the recovery of a firearm.
The Fifth Circuit held that using license plate reader technology to identify and locate a vehicle does not constitute a Fourth Amendment search.
-
Individuals have no reasonable expectation of privacy in license plates or in a vehicle’s movements on public roads.
Seventh Circuit – United States v. Suggs
Good-Faith Mistakes in Warrants May Still Be Upheld
Mar. 17, 2026
-
Agents executed a search warrant at what they reasonably believed was a single-family home. Only later did they learn the property was actually a multi-unit building. That error stemmed from pre-search checks that, at the time, reasonably suggested it was a single residence.
The court upheld both the warrant and the search.
-
If officers conduct a thorough, good-faith investigation beforehand, courts may overlook reasonable mistakes in the warrant’s factual assumptions.
California Court of Appeal – People v. Perez
Vehicle Impounds Must Be Tied to a Genuine Community Caretaking Need
March 19, 2026
-
An officer stopped a driver for a municipal code violation and learned the driver had a suspended license. The vehicle, however, was legally parked and posed no hazard or obstruction. Despite this, the officer impounded the vehicle and conducted an inventory search, uncovering drugs, cash, and later additional evidence.
The court ruled the impound unconstitutional because it lacked a valid community caretaking purpose. A suspended or unlicensed driver, by itself, does not justify impoundment.
-
Officers cannot impound a vehicle solely because the driver is unlicensed or has a suspended license. There must be a specific, articulable community caretaking reason.
(Examples: Suspicion of criminal activity, disabled vehicle in the breakdown lane, sobriety checks, reports of shots fired or weapon possession.)
New York Court of Appeals – People v. Jones
Mistaken Identity Still Requires Specific, Reasonable Suspicion
March 17, 2026
-
Parole investigators searching for a wanted person encountered a man they believed might be the suspect. He generally resembled the wanted individual and fled when plainclothes investigators in unmarked vehicles approached. Officers pursued him, observed him discard a firearm, and arrested him, only later learning he was not the wanted person.
The Court of Appeals ruled that the pursuit and arrest were unconstitutional because the officers lacked sufficiently specific facts to justify the stop. In these circumstances, a vague physical resemblance combined with flight did not meet the standard of reasonable suspicion.
-
A general resemblance to a suspect is not enough to justify a stop or pursuit. Even when a person flees, officers must have specific, articulable facts tying that individual to the wanted person or to criminal activity.
Alabama Supreme Court – Jennings v. Smith
Officers May Request Physical Identification During a Lawful Stop
March 13, 2026
-
Officers responded to a welfare check and encountered a man at a neighbor’s house. He claimed he was watching the home for the owners but became agitated and refused to provide identification when asked. After repeatedly refusing to identify himself, he was arrested.
The Alabama Supreme Court clarified that during a lawful Terry stop, officers are not limited to accepting incomplete verbal identification.
-
During a lawful stop, officers can request physical identification, particularly when the person offers incomplete or unclear identifying information. This case clarifies the difference between simply asking for a name and requesting enough information to reasonably confirm someone’s identity.
California Court of Appeal – Meiner v. Superior Court
Probation Search Limits (Digital / Financial)
March 18, 2026
-
A probationer under investigation for theft-related conduct had his phone searched pursuant to his probation terms. During the search, officers accessed his Apple Pay account, discovered linked bank cards, and then used that information to obtain a warrant for the related bank records.
The Court of Appeal held this was improper because the probation search terms expressly excluded financial accounts and transactions, and that limitation was omitted from the warrant application in a way the court deemed material.
-
Probation search conditions do not automatically authorize access to all digital information. When probation terms exclude financial accounts or transactions, officers must honor those limits in conducting phone and other electronic searches.
Minnesota Supreme Court – State v. Smeby
Some Medical & Paramedic Statements May Still Be Reachable in DUI Cases
March 18, 2026
-
After a crash, officers found a driver unconscious behind the wheel. Narcan was administered, and he was transported to the hospital. During treatment, he made statements about heroin use to paramedics and to his girlfriend, who then relayed information to medical staff. Officers later obtained a search warrant for his medical records and ambulance documentation.
The Minnesota Supreme Court held that these statements were not automatically protected by medical privilege in this context. The Court also concluded that the warrant for the records was sufficiently particular.
-
Statements made in the course of emergency medical response are not always covered by medical privilege. Particularly when made to people outside the protected treatment relationship or when the privilege does not clearly apply. This is especially important in DUI, overdose, and other impairment investigations involving medical evidence.
D.C. Circuit – United States v. Thorne
Good-Faith Reliance Can Preserve Evidence From a Flawed Tracking Warrant
March 17, 2026
-
In a drug and firearm trafficking investigation, officers obtained warrants to track the defendant’s phones using GPS pings and a cell-site simulator. The defendant later claimed a Rule 41 violation, arguing there was insufficient evidence that the phone was located within the issuing court’s district when the warrant was issued.
The D.C. Circuit declined to decide the Rule 41 issue directly. Instead, it held that suppression was inappropriate because the officers acted in good-faith reliance on the warrant.
-
Even when a tracking warrant is later challenged for technical defects, evidence may still be admissible if officers relied on it in good faith.
Providing key protection for investigations involving phone tracking and similar surveillance technologies.
Montana Supreme Court – State v. Flores-Reyes
Consent Searches Do Not Automatically Include Hidden Containers
March 17, 2026
-
After obtaining the owner’s consent to search a vehicle, officers accessed a concealed compartment and opened a closed pouch containing narcotics. The Montana Supreme Court held that this went beyond the scope of the consent provided.
-
A general consent to search a vehicle does not, by itself, authorize officers to open closed containers or search hidden compartments without additional justification or explicit consent.
