Also known as: objective reasonableness · objectively-reasonable · reasonable officer standard
Written by attorneys · grounded in primary & secondary sources — see below
A standard that evaluates an actor's conduct or belief according to what a reasonable person would have done or believed under the same circumstances. The inquiry focuses on the facts known to the actor at the time and disregards the actor's actual intent or motivation.
Orlando Okafor consented to a search of his vehicle for drugs without any stated limits. Officers opened a closed duffel bag in the trunk and found narcotics. The court upheld the search because an officer could reasonably interpret the consent to include areas where drugs might be hidden.
Odilia Okamura learned that her spouse had been unfaithful and immediately confronted the spouse. After several minutes of heated argument she struck and killed the spouse. The factfinder determined that an ordinary person would still have been inflamed and that Okamura had not cooled off before acting.

Officers obtained a warrant that contained a typographical error in the address caused by the issuing judge's clerk. They executed the warrant in good faith and seized evidence. The court admitted the evidence because the officers' reliance on the warrant's facial validity was objectively reasonable.
Olive Okafor's home was searched under a warrant later found to lack probable cause. The officers had relied on the neutral magistrate's issuance of the warrant without any indication of facial deficiency or misconduct. The court refused to suppress the evidence because the officers' reliance was objectively reasonable.
Orla O'Malley was stopped for a traffic violation and appeared nervous while reaching toward the passenger compartment. Officers conducted a limited search of that area for weapons. The court upheld the search because the officers held an articulable and objectively reasonable belief that the suspect could access a weapon.
Ophelia O'Brien agreed to sell what she believed were counterfeit goods to undercover officers. She did not realize the buyers were federal agents. The court held that her conviction did not require proof she knew the buyers' official status because the objective facts supported the conspiracy charge.
The standard asks what a reasonable officer or person would have believed or done under the known facts rather than what the particular actor actually believed. Courts therefore disregard the actor's personal motivations or honesty when applying the test.

Yes. The same objective lens is used to judge whether an officer's reliance on a warrant was reasonable and whether a defender's belief in imminent harm was reasonable. In both settings the inquiry ignores the actor's actual intent.

The test requires that an ordinary person would have been provoked and would not yet have cooled off. It also requires that the defendant actually became provoked and did not cool off, but the cooling-off element is judged by the ordinary-person benchmark.
