 The dissent believed that probable cause hearings should generally be provided much sooner, as soon as the police complete the administrative steps incident to arrest.The "County of Riverside v. McLaughlin" (1991) case was a court case dealing with the interpretation of the Fourth Amendment of the United States Constitution in a probable cause case involving a warrantless arrest.In this instance, the Fourth Amendment is used by the plaintiff(s) to argue that the clause “warrants must be legally justified with probable cause” also applies to "warrantless" arrests because it was implied that it would be unreasonable, if not "unconstitutional", for someone to be arrested without determining probable cause.
