How is "probable cause" defined in a legal context?

"Probable cause" is defined as a reasonable belief based on facts that a crime has been committed. This standard is essential in the legal context, especially for law enforcement and judicial actions, such as obtaining search warrants or making arrests. The notion of probable cause encompasses more than mere suspicion; it requires more substantial evidence that suggests a crime has likely occurred.

For example, if a police officer observes someone engaging in suspicious behaviors, coupled with other corroborating evidence, that officer might establish probable cause to believe a crime has been committed. This is a critical threshold because it balances the need for law enforcement to act and the rights of individuals against unreasonable searches and seizures. In contrast, mere suspicions or witness statements do not meet the criteria necessary for probable cause without supporting factual evidence.
