In 1928, Roy Olmstead was prosecuted for violating Prohibition by importing and supplying alcoholic beverages. He appealed his conviction, arguing that evidence obtained from warrantless wiretaps of his phone conversations violated his 4th and 5th Amendment rights. In Olmstead v. United States, the Supreme Court ruled 6-3 that the 4th Amendment did not prohibit warrantless wiretapping as there was no physical search or seizure of evidence. However, Justice Brandeis dissented, arguing that individuals are entitled to privacy in their communications and government overreach threatens civil liberties. This ruling was later overturned in 1967.
