Whether Secret Service agents were entitled to qualified immunity from Bryant’s claim that they arrested him without probable cause to believe he had threatened the President.
Holding
Yes. The agents were entitled to qualified immunity because a reasonable officer could have believed that probable cause existed, even if that belief was ultimately mistaken.
Reasoning
Qualified immunity protects an officer if a reasonable officer could have believed the arrest lawful in light of clearly established law and the information then available. Under Anderson v. Creighton, the protection extends to officers who reasonably but mistakenly conclude that probable cause exists. The issue was therefore not whether the agents’ interpretation of Bryant’s statements was the best possible interpretation in hindsight.
At the time of arrest, the agents had trustworthy information that Bryant had written a letter referring to an assassination plot against the President, knew that the President was then in Germany, had reportedly said that the President should have been assassinated in Bonn, had made statements about assassination and a throat-cutting gesture, and refused to answer whether he intended to harm the President. Those undisputed facts made the agents’ conclusion objectively reasonable.
The Court did not need definitively to decide whether actual probable cause existed. Even assuming that the agents and the magistrate had been wrong to find probable cause, qualified immunity still applied because their judgment was reasonable rather than plainly incompetent or a knowing violation of the law.
The Court stressed that qualified immunity allows room for reasonable mistakes. That allowance is especially important when officers confront information suggesting a possible threat to the President, because officials should not be forced to underreact solely out of fear of personal damages suits.
