What Will US Supreme Court Decide About Cell Phone Locational Privacy?

 Attorney Terrence P. Dwyer writes that there is still a question left open by the U.S. Supreme Court "relating to the extent of government use of GPS technology without a warrant, specifically about requirements when there is no physical trespass upon personal property." He writes that some courts are more protective of cell site locator information while others are not (CSLI "can be sought in one of two ways — either as historical cell site data that seeks past locator information, or as prospective cell site data which seeks real time, present data"). He also writes that it is likely the courts, not legislatures will decide the parameters of our privacy regarding cell phones locational data as there has been very few bills introduced to govern this subject area.
