Beyond the Snapshot: Supreme Court Resets Standard in Deadly Traffic Stop Case

When Deadly Force Meets Constitutional Limits: SCOTUS Reverses Lower Court in Landmark Excessive Force Case

In a powerful and unanimous decision, the U.S. Supreme Court recently delivered a critical reminder to lower courts: assessing excessive force claims under the Fourth Amendment demands a full, contextual evaluation—not a snapshot in time.

This ruling, issued in Barnes v. Felix, revives a civil rights lawsuit filed by the mother of Ashtian Barnes, a Black man fatally shot by a police officer during a 2016 traffic stop near Houston, Texas. The opinion, penned by Justice Elena Kagan, challenges a controversial approach used by the U.S. Court of Appeals for the Fifth Circuit—one that has effectively narrowed the scope of constitutional scrutiny to mere seconds surrounding a use-of-force incident.

The Court’s decision not only breathes life into Janice Hughes Barnes’s long-fought legal battle but may also redefine how courts across the country analyze deadly encounters involving law enforcement.


Case Background: A Routine Stop Turns Deadly

The incident began when Officer Roberto Felix of the Harris County Constable’s Office stopped a Toyota Corolla driven by Ashtian Barnes. The vehicle, a rental car belonging to Barnes’s girlfriend, had triggered a radio alert due to unpaid tolls. Barnes, on his way to pick up a child from daycare, admitted he did not have his license with him.

When asked to step out of the vehicle, Barnes initially complied but then abruptly re-entered the car and began to drive away—with the driver’s door still open. Officer Felix, reportedly standing on the doorsill at the time, fired two fatal shots into the moving car. Barnes died on the scene. The incident was captured by dashcam footage.

In the aftermath, Barnes’s mother filed a federal civil rights lawsuit, asserting that Felix had violated her son’s Fourth Amendment right against the use of excessive force.


Lower Courts Focused Too Narrowly

The federal district court and the Fifth Circuit Court of Appeals dismissed the lawsuit, relying heavily on a doctrine known as the “moment-of-threat” test. According to this standard, courts are to assess only the moment when deadly force was applied—effectively ignoring all events leading up to it.

The Fifth Circuit concluded that Felix’s use of force was reasonable during the critical two seconds when he stood on the vehicle’s running board as it moved forward. In that window, the court found, Felix could have reasonably perceived a threat to his safety.

Judge Patrick Higginbotham, in a separate opinion, expressed concern about this reductionist approach, noting that “a routine traffic stop has again ended in the death of an unarmed Black man.” He warned against ignoring the broader circumstances of such deadly encounters.


SCOTUS Weighs In: Look at the Bigger Picture

Justice Elena Kagan, writing for the unanimous Court, firmly rejected the Fifth Circuit’s narrow lens. She emphasized that evaluating excessive force under the Fourth Amendment requires a comprehensive, fact-specific inquiry into “the totality of the circumstances.”

Key points from the opinion:

  • No Time Limit on Contextual Analysis: Kagan wrote that “such an inquiry has no time limit.” Courts must consider all relevant facts, including those leading up to the moment deadly force was used.
  • Chronological Blindness Is Unconstitutional: Courts that “put on chronological blinders” are unable to properly assess whether an officer’s use of force was reasonable, Kagan argued. The totality-of-circumstances test cannot be compressed into a two-second review.
  • Even the Officer Didn’t Defend the Lower Court’s Approach: Notably, even Officer Felix did not defend the Fifth Circuit’s rigid timing rule, instead arguing that it was misapplied. Kagan responded that regardless, “the decisions below applied a rule about timing,” and that alone was grounds for reversal.

Importantly, the Court did not make a final determination about whether Felix’s conduct was unreasonable under the Fourth Amendment. Instead, the case has been remanded back to the Fifth Circuit to reconsider the facts under the broader, correct legal standard.


Concurring Views and Future Implications

In a concurring opinion, Justice Brett Kavanaugh—joined by Justices Thomas, Alito, and Barrett—highlighted the dangers police officers face during traffic stops. He urged lower courts to factor in not just the moment deadly force is applied, but also whether the suspect’s attempts to flee created risks to public and officer safety.

While Kavanaugh’s concurrence supports the majority’s broader timeline approach, it also signals a cautionary note: officers face real threats, and the Fourth Amendment must be interpreted with that in mind.


Why This Decision Matters

This ruling could significantly alter how excessive force claims are evaluated—especially in police shooting cases involving Black and minority victims. By rejecting the “moment-of-threat” doctrine, the Supreme Court reaffirmed the constitutional requirement to analyze all relevant events leading up to a deadly encounter.

For civil rights attorneys, criminal defense lawyers, and constitutional scholars, the Court’s decision is both a course correction and a warning: oversimplified legal standards that condense complex police-citizen interactions into seconds are not just inadequate—they’re unconstitutional.


Key Takeaways for Legal Practitioners and Law Students

  1. Totality of the Circumstances Matters: Don’t rely solely on the moment deadly force is used—context, escalation, and officer conduct all play into constitutional reasonableness.
  2. Challenges to Summary Judgments May Increase: With this ruling, plaintiffs in excessive force cases have stronger grounds to challenge dismissals at early stages.
  3. Race and Policing Remain Central: The Court’s decision implicitly acknowledges the gravity of racial disparities in law enforcement, even if it doesn’t address race directly.
  4. Appellate Scrutiny is Shifting: Watch for more aggressive appellate reviews of lower court standards, especially when they diverge from established constitutional tests.
