Which case relates to probable cause to arrest?

The case of Brinegar v. United States is significant in the context of probable cause to arrest because it established criteria for evaluating whether law enforcement had sufficient grounds to make an arrest. In this landmark decision, the court emphasized that probable cause exists when the facts and circumstances within the officer's knowledge are sufficient to warrant a belief by a reasonable person that a suspect has committed a crime.

The ruling clarified the standards that must be met for officers to justify an arrest or a search, emphasizing the importance of a totality-of-the-circumstances approach. This involves considering all the facts collectively, rather than in isolation, to determine if probable cause is established. Thus, Brinegar v. United States provides essential legal precedent that guides law enforcement practices concerning arrests based on probable cause.
