In Ogden, Utah, when the Sheriff’s Department wants information on a cellphone, it leaves it up to the carrier to determine what the sheriff must provide. “Some companies ask that when we have time to do so, we obtain court approval for the tracking request,” the Sheriff’s Department said in a written response to the A.C.L.U.
And in Arizona, even small police departments found cell surveillance so valuable that they acquired their own tracking equipment to avoid the time and expense of having the phone companies carry out the operations for them. The police in the town of Gilbert, for one, spent $244,000 on such equipment.
