Federal authorities will make their case before federal judges that warrantless tracking of cell phone locations is legal, CNET reports.
Federal prosecutors don’t want to ask a judge to approve a warrant before obtaining stored records that reveal the constant movements of mobile phone users over a two-month period, according to CNET.
Location data are useful for police because people almost always carry their cell phones with them, CNET reports.
But many think the warrantless tracking is a violation of privacy rights and should only done with approval from a judge.
