During the mid-20th century, Niagara Falls, New York, gained a reputation as the most heavily wiretapped and surveilled city in the United States. Intense FBI and law enforcement monitoring was tied to local organized crime, gambling rackets, and mob activity rooted in Western New York. Federal and state agencies relied heavily on electronic surveillance and wiretaps to investigate racketeering, smuggling, and corruption, especially in the 1960s. Federal wiretapping laws underwent a massive transformation beginning in the late 1960s, shifting from an unregulated, legally gray environment into a highly structured framework requiring strict judicial oversight. Before this era, the Supreme Court ruled that wiretapping didn’t require a warrant if physical property wasn’t accessed. That allowed law enforcement to monitor phone lines outside suspects’ homes relatively freely.
