This very important case has had a defining impact on the US criminal justice system because it affects the way criminal suspects are handled upon arrest and before a trial. The rule prevents a violation of the Fifth Amendment of the US Constitution by protecting suspects from self-incrimination. The courts always have to deal with the issue of whether or not evidence against a suspect was properly collected. This includes statements or confession made by a suspect before or at the time of his arrest and before questioning by the police. These are important issues that raise questions about when one becomes a prime suspect and in fact, when one becomes a suspect.
