getting a warrant because their entry "was plainly reasonable under the circumstances." In ruling the officers' entry was supported by exigency, the Court cited Mincey v. Arizona, , 393–394: [W]arrants are generally required to search a person’s home or his person unless 'the exigencies of the situation' make the needs of law enforcement so compelling that the warrantless search is objectively reasonable under the Fourth Amendment." ... One exigency obviating the requirement of a warrant is the need to assist persons who are seriously injured or threatened with such injury. ... Accordingly, law enforcement officers may enter a home without a warrant to render emergency assistance to an injured occupant or to protect an occupant from imminent injury. Mincey, supra, at 392; see also Georgia v. Randolph, 547 The court found that "the officers had an objectively reasonable basis for believing both that the injured adult might need help and that the violence in the kitchen was just beginning." "Knock and announce" rule The Court found that "the manner of the officers' entry was also reasonable." The court found that after seeing the punch, one officer opened the screen door to the kitchen and yelled in "police." Upon nobody hearing him, he stepped into the kitchen and then announced himself again, which prompted the tumult to subside. The Court ruled that: ...the officer's announcement of his presence was at least equivalent to a knock on the screen door. Indeed, it was probably the only option that had even a chance of rising above the din. Under these circumstances, there was no violation of the Fourth Amendment’s knock-and-announce rule. Also, the Court ruled that once the officers announced their presence, they were free to enter the house to deal with the tumult, as it would be pointless to stand at the door waiting for a response while people brawled inside.
