What is the definition of probable cause?

Probable cause is defined as a set of facts or circumstances that would lead a reasonable person to believe that a crime has been committed and that the suspect is involved in that crime. It reflects a level of certainty that goes beyond mere suspicion or speculation. In legal contexts, this threshold is crucial because it is required to justify actions such as arrests or the issuance of search warrants.

Establishing probable cause often involves evaluating the totality of circumstances, including observations, evidence, and reliable information obtained by law enforcement. This distinction is important because it is based on factual evidence rather than assumptions or mere beliefs, ensuring that the rights of individuals are protected while allowing law enforcement to act on legitimate concerns regarding criminal activity.
