Herring v. United States
Headline: Court allows evidence from an arrest caused by an isolated police recordkeeping mistake, limiting when courts will suppress evidence and making exclusion less likely.
Holding: When an unlawful arrest results from isolated, negligent recordkeeping errors attenuated from the arrest, the exclusionary rule does not apply and the evidence need not be suppressed.
- Makes courts less likely to suppress evidence after isolated police database errors.
- Allows drugs and guns found after such arrests to be used at trial.
- Pushes police agencies to improve recordkeeping to avoid admissibility disputes.
Summary
Background
On July 7, 2004, a law enforcement investigator in one county checked a neighboring county’s warrant database and was told an arrest warrant for Bennie Dean Herring was active. When officers arrested Herring and searched him, they found methamphetamine and a pistol. Later the database error was discovered: the warrant had been recalled months earlier but never removed from the sheriff’s computer records. Herring was charged in federal court and asked to block the drugs and gun from evidence because his arrest had been unlawful.
Reasoning
The Supreme Court accepted that the arrest violated the Fourth Amendment but focused on whether the exclusionary rule — the court-made rule that can bar unlawfully obtained evidence — should apply. The Court weighed how blameworthy police conduct was and whether excluding evidence would deter future mistakes. It found the error was an isolated, negligent recordkeeping failure attenuated from the arrest, not a deliberate or systemic effort to evade the Constitution. Relying on prior cases, the Court held that marginal deterrent benefits do not justify the heavy costs of suppressing evidence here.
Real world impact
Because of this ruling, evidence found after an arrest based on a single negligent database mistake can remain admissible when officers reasonably relied on records. The decision encourages courts to weigh police culpability before excluding evidence and signals that suppression is reserved for deliberate, reckless, or widespread errors. Lower courts and police agencies will now evaluate recordkeeping practices and patterns to determine suppression risks.
Dissents or concurrances
A four-Justice dissent argued the exclusionary rule should apply to deter careless recordkeeping and protect innocent people from wrongful arrests; another Justice joined that view.
