Back in the United States, the Supreme Court has ruled the Constitution does not require prosecutors to forfeit evidence obtained through so-called “no knock” illegal searches. The five to four vote will strengthen police’s abilities to enter residences without announcing themselves first. The court ruled the social costs of throwing out illegally-obtained evidence outweighed the benefits of protecting previous safeguards. In a dissenting opinion, Justice Stephen Breyer wrote: “The majority’s 'substantial social costs' argument is an argument against the Fourth Amendment’s exclusionary principle itself. And it is an argument that this Court, until now, has consistently rejected.”
