The defendant attempted to intercept electronic communications in alleged violation of 18 U.S.C § 2511 (1) (a), known as the Wiretap Act. This Act was written to protect the privacy of electronic, oral, and wire communications. The defendant installed a device called a KeyKatcher. This device was placed on the cable that connects the keyboard to the central processing unit (CPU). The KeyKatcher records the electronic impulses that are sent to the CPU when a key is depressed. These impulses can be translated into text so that a transcript of everything that was typed can be obtained. The court addressed the issue of whether Ropp was liable under the Wiretap Act for intercepting “electronic communications”. The Act defined “electronic communications” as “any transfer of signs, signals, writing, images, sounds, data, or intelligence of any nature transmitted in whole or part by a wire, radio, electromagnetic, photoelectric or photooptical system that affects interstate or foreign commerce”. 18 U.S.C § 2511 (1) (a). Ropp argued that because the intercepted communications only took place on a local system, the communications did not affect “interstate or foreign commerce”.
