What does the term 'probable cause' refer to?

The term 'probable cause' refers to a reasonable basis for believing that a crime may have been committed. This concept is crucial in the legal system, particularly in relation to law enforcement and the judicial process. Probable cause is the standard used to justify arrests and the issuance of search or arrest warrants. It implies that there are sufficient facts or evidence to support the belief that a crime has occurred, making it necessary for law enforcement to act.

In contrast to a higher standard such as "beyond a reasonable doubt" which is used during criminal trials to establish guilt, probable cause requires only a reasonable belief supported by evidence that a crime may have taken place. This standard balances the need to protect the community and uphold the law while also safeguarding individuals' rights against arbitrary actions by authorities.
