What Does “Totality of the Circumstances” Really Mean?

By Robert Phillips
Deputy District Attorney (Ret).

Totality of the Circumstances: Ever wonder what the term “totality of the circumstances” really means   It seems so obvious that we seldom even think about it.  It’s typically used in appellate court cases dealing with the legality, or constitutionality, of a police officer’s use of force. But it’s also been used when attempting to define the legal term “probable cause.” (E.g., see Illinois v. Gates (1983)  462 U. S. 213, 232.)  It also applies when defining a “reasonable suspicion” in discussions about the legality of a detention, or what’s sometimes referred to as a “Terry stop” per Terry v. Ohio (1968) 392 U.S. 1. (See People v. Casares (2016) 62 Cal.4th 808, 837-838.) Most recently, however, it was the subject of a U.S. Supreme Court case dealing with a law enforcement officer’s potential civil liability in a use-of-force case. 

In Barnes v. Felix (May 15, 2025) 605 U.S. 73, a police officer attempted to prevent the driver of a lawfully stopped vehicle from driving away. As the subject tried to drive off, the officer was holding onto the driver’s side open door, leaning into the vehicle; a situation the court later determined to be very dangerous.  As the subject attempted to drive away, the officer shot him twice, killing him.

A federal district court in Texas upheld the trial court’s finding that the officer was entitled to qualified immunity from civil liability, ruling that “at the moment of the threat,” the officer was in reasonable fear for his life. The Fourth Circuit Court of Appeals upheld this decision, using the same test for determining the reasonableness of the officer’s use of deadly force. (See Barnes v. Felix (4th Cir. 2024) 91 F.4th 393.) Appealed to the U.S. Supreme Court, the High Court affirmed despite the fact that the lower courts both used the wrong test. Specifically, the Supreme Court held that the “moment of the threat” test is not nearly broad enough when determining the reasonableness of a ....
