As a result, it was decided that the agents violated the Fourth Amendment when they used electronic surveillance to listen in on the suspect Charles Katz without a warrant. The Federal Bureau of Investigation suspected him of playing a role in an illegal gambling operation. They observed him using a public payphone and believed he was transmitting information to a known gambler in Massachusetts. They confirmed their suspicions by acquiring a record of the numbers he called while using the phone booth. Katz was arrested on eight counts, which included illegal transmission of wagering information across state lines. A court overturned the evidence against Katz because it was collected unconstitutionally. Katz case extends protections against unreasonable searches and seizures of electronic wiretapping devices. A further rule related to the Fourth Amendment is that each search or seizure should be cleared in advance by a judge, and to get a warrant the government must show “probable cause”, meaning any evidence is in plain sight, on public media, or acquired
