Using special software, South Dakota law enforcement officers found a person who appeared to possess child pornography at a specific Internet protocol address. The officers subpoenaed Midcontinent Communications, the service that assigned the address, for the personal information of its subscriber. With this information, the officers obtained a search warrant for the residence of John Rolfe, where they found a laptop that contained child pornography. Rolfe argued that the subpoenas violated his “expectation of privacy.” Did Rolfe have a privacy interest in the information obtained by the subpoenas issued to Midcontinent? Discuss.
