What Is Probable Cause?Probable cause is a reasonable belief that a person has committed or will commit a crime. For probable cause to exist, a police officer must have sufficient knowledge of facts to warrant a belief that a suspect is committing a crime. The belief must be based on factual evidence, not just on suspicion. The test which the court employs to determine probable cause is whether an objective person of reasonable intelligence would believe that the circumstances indicate that the person arrested or detained has committed a crime. Sources of Probable CauseThere are four categories of evidence which may establish probable cause: - Observation - Information obtained by an officer through observation
- Circumstantial evidence - Indirect evidence that implies something occurred but does not directly prove it ¿ the circumstances surrounding the facts can be used to reasonably infer guilt or innocence
- Expertise - The training of police officers which enables them to identify certain movements, gestures, preparations, or tools as tending to indicate criminal activity
- Information - Includes statements by witnesses, victims, and informants
When Can a Search, Seizure, or Arrest OccurIn general, probable cause must exist before a search, seizure, or arrest by law enforcement. Search warrants and arrest warrants are only issued upon a finding of probable cause, and warrantless searches or arrests must meet the standard of probable cause to be admissible in court. Searches, Seizures, and Arrests without Probable CauseEvidence directly obtained as a result of a search, seizure, or arrest that occurred without probable cause cannot be used in court against a defendant. In addition, evidence that would not have been obtained but for the illegal search, seizure or arrest may also be inadmissible at trial.
