Why did Katz sue the US?

Answer 1

Katz sued the U.S. government primarily over the legality of wiretapping. He argued that the FBI had violated his Fourth Amendment rights by conducting warrantless surveillance of his phone calls, which he claimed were private communications. The case ultimately reached the Supreme Court, leading to a landmark decision that affirmed the need for a warrant for wiretaps, reinforcing privacy rights against government intrusion. This ruling established the principle that the Fourth Amendment protects people, not just places, from unreasonable searches and seizures.
