Misconduct by law enforcement officers that involves deliberate or reckless constitutional violations. Such conduct triggers the exclusionary rule when the deterrent value of suppression outweighs its social costs, as determined by the officers' culpability.
Officers entered a hospital on-call room through security without a warrant and spotted a duffel bag of opioids. They left without seizing it and later obtained a warrant based solely on pharmacy records. The court admitted the evidence because the initial entry reflected isolated negligence rather than deliberate overreaching that would trigger suppression.
State officers conducted a warrantless search of a home and seized evidence later used in a criminal trial. The defendant moved to exclude the items on constitutional grounds. The court suppressed the evidence because the officers' violation of the Fourth Amendment constituted overreaching that the exclusionary rule must deter in state proceedings.

Leo walked into the station and confessed after receiving Miranda warnings. Detective Harris asked no questions and made no threats or promises despite knowing of Leo's psychotic disorder. The court found no overreaching and admitted the statement because the absence of official pressure left the confession voluntary.
An officer approached Peter Park on the street and asked brief questions after observing suspicious behavior. The encounter remained short and nonthreatening. The court held that the limited interaction did not rise to overreaching that would require suppression of any resulting evidence.
Federal agents entered Pavel Petrov's apartment without a warrant and seized evidence. Petrov sued the agents for damages under the Constitution. The court recognized a remedy because the agents' deliberate intrusion amounted to overreaching that violated Fourth Amendment protections.
Officers pursued Preston Pratt's vehicle at high speed after a minor traffic violation. The chase ended in a crash that killed a passenger. The court found no overreaching because the officers did not intend to cause harm and therefore faced no due-process liability.
No. Mental illness or impaired free will can be relevant only when it interacts with coercive police conduct. Without official overreaching that overbears the suspect's will, a confession remains voluntary under the Due Process Clause even if the suspect suffers from psychosis.

Isolated or merely negligent misconduct does not trigger suppression when the deterrent value of exclusion is outweighed by its social costs. Courts examine the culpability of the officers and whether exclusion would meaningfully deter future violations.

The exclusionary rule prohibits use of evidence obtained through Fourth Amendment violations in state criminal trials. It deters police misconduct by rendering such evidence inadmissible just as it would be in federal court.

…must be laid down, requiring the presence of counsel at all pretrial identifications, in order to detect recurring instances of police misconduct.[^maj-1] I do not share this pervasive distrust of all official investigations. None of the materials the Court relies upon supports it.[^maj-2] Certainly, I would bow to solid fact, but…
