Justice Ginsburg, dissenting - Kentucky v. King, 563 U.S. ____ (2011):
The Court today arms the police with a way routinely to dishonor the Fourth Amendment ’s warrant requirement in drug cases. In lieu of presenting their evidence to a neutral magistrate, police officers may now knock, listen, then break the door down, nevermind that they had ample time to obtain a warrant. I dissent from the Court’s reduction of the Fourth Amendment ’s force. The Fourth Amendment guarantees to the people “[t]he right … to be secure in their … houses … against unreasonable searches and seizures.” Warrants to search, the Amendment further instructs, shall issue only upon a showing of “probable cause” to believe criminal activity is afoot. These complementary provisions are designed to ensure that police will seek the authorization of a neutral magistrate before undertaking a search or seizure. Exceptions to the warrant requirement, this Court has explained, must be “few in number and carefully delineated,” if the main rule is to remain hardy. United States v. United States Dist.
