The Fourth Amendment of the United States Constitution plays a crucial role in establishing the legal framework for arrests by requiring probable cause. This means that law enforcement must have a reasonable belief that a person is involved in criminal activity before making an arrest.

For warrantless arrests, this standard means that officers must be able to articulate facts and circumstances leading them to believe that a crime has been, is being, or will be committed. Probable cause ensures that individuals are not arrested arbitrarily or without sufficient justification, which protects them from unreasonable searches and seizures.
