Baltimore Police balk when pressed by judge on phone tracking capabilities - Baltimore Sun
City police Det. John L. Haley, a member of a specialized phone tracking unit, said officers did not use the controversial device known as a stingray. But when pressed on how phones are tracked, he cited what he called a "nondisclosure agreement" with the FBI. "You don't have a nondisclosure agreement with the court," Baltimore Circuit Judge Barry G. Williams replied. Williams threatened to hold Haley in contempt if he did not respond. Prosecutors decided to withdraw the evidence instead.
