“ With the benefit of hindsight and calm deliberation, the panel majority concluded that it was unreasonable for petitioners to fear that violence was imminent. But we have instructed that reasonableness "must be judged from the perspective of a reasonable officer on the scene, rather than with the 20/20 vision of hindsight" and that " [t] he calculus of reasonableness must embody allowance for the fact that police officers are often forced to make split-second judgments—in circumstances that are tense, uncertain, and rapidly evolving." ”

“ Huff had consented, but reversed as to petitioners. The majority upheld the District Court's findings of fact, but disagreed with the District Court's conclusion that petitioners were entitled to qualified immunity. The majority acknowledged that police officers are allowed to enter a home without a warrant if they reasonably believe that immediate entry is necessary to protect themselves or others from serious harm, even if the officers lack probable cause to believe that a crime has been or is about to be committed. ”

“ Third, the panel majority's method of analyzing the string of events that unfolded at the Huff residence was entirely unrealistic. The majority looked at each separate event in isolation and concluded that each, in itself, did not give cause for concern. But it is a matter of common sense that a combination of events each of which is mundane when viewed in isolation may paint an alarming picture. ”
