Prosecutors say evidence, including a gun magazine and notebook, was obtained in a warrantless backpack search after Mangione's arrest at a Pennsylvania McDonald's.

History

Historical Context

The 1961 Supreme Court case Mapp v. Ohio established the exclusionary rule, which prevents the use of illegally obtained evidence in court, applying it to state courts through the Fourteenth Amendment. This landmark decision built on earlier cases like Weeks v. United States (1914) and Wolf v. Colorado (1949), reshaping law enforcement practices and reinforcing Fourth Amendment protections against unreasonable searches.
