The twenty-first century has ushered in demand by some Americans for annoyancetech devices—novel electronic gadgets that secretly fend off, punish, or comment upon perceived antisocial and annoying behaviors of others. Manufacturers, marketers, and users of certain annoyancetech devices, however, face potential tort liability for personal and property damages suffered by the targets of this “revenge by gadget.” Federal, state, and local policymakers should start the process of coming to pragmatic terms with the troubling rise in the popularity of annoyancetech devices. This is an area of social policy that cries out for thoughtful and creative legislative solutions.
