Since there are few legal limitations on private industry surveillance of private citizens, could the government contract surveillance to private companies? Would this be legal? Would it be desirable? Recall that there is a national “do not call” number with which consumers can register to opt out of telemarketing. Could the same type of centralized system be implemented to allow consumers to opt out of spam? Why or why not? The government’s ability to wiretap is limited by the Federal Wiretap Act. Is private industry allowed to wiretap? Why has legislation never been enacted restricting access to personal data by private industry?
