467 U.S. 649 (1984)
A woman told police officers that she had been raped, described the assailant, and told them that he was in a nearby grocery store, carrying a gun. One of the officers chased the defendant through the store and, when he apprehended him, the defendant was wearing an empty holster. The officer asked where the gun was and the defendant revealed its location. The officer retrieved the gun, formally arrested the defendant, and read him the Miranda warnings.
The United States Supreme Court crafted an exigency-based “ ‘public safety’ exception to the requirement that Miranda warnings be given before a suspect’s answers may be admitted into evidence,” reasoning that officers may otherwise hesitate to ask questions necessary to protect public safety out of a concern that any evidence uncovered will be inadmissible.
