What does "probable cause" refer to in law enforcement?

Probable cause refers to a reasonable belief that a crime has been committed, which is a foundational principle in law enforcement and the criminal justice system. This standard is more than just a mere suspicion or hunch; it requires facts or evidence that would lead a reasonable person to believe that a specific individual has engaged in criminal activity. This concept is critical in obtaining warrants and making arrests, as it helps to ensure that the rights of individuals are protected by preventing arbitrary actions by law enforcement.

For example, if officers observe someone engaging in behaviors consistent with drug dealing, such as exchanging packages with known users at unusual hours, this could provide probable cause for an arrest. The belief must be supported by factual evidence rather than personal feelings or opinions, thus maintaining the integrity of the legal process. This is why the other options do not accurately capture the legal definition; they either reflect a lesser standard or rely on subjective judgments rather than objective facts.
