DA Moore hopeful FBI’s stance on unlocking iPhones will help in local criminal case

"Riana Pfefferkorn, a cryptography fellow at Stanford Law School’s Center for Internet and Society, noted that the FBI signed similar agreements with a third party to use so-called “Stingray” technology, which, in effect, impersonates a cellphone tower to pick up phone calls.

She said such third party outsourcing deals raise issues.

“You know it (outsourcing) might end up tying the government’s hands when they obtain tools that will end up being potentially limited in their use to the extent that they are not able to meet federal or state court evidentiary standards for authenticating the tools and how they work,” Pfefferkorn said."
