The San Francisco Police Department is pursuing a "fear and distrust" strategy in an attempt to wreck the city's black market for mobile devices, particularly iPhones, the Huffington Post writes. Sting operations are targeting both the buyers and sellers of stolen devices, the idea being to deter people from going the illegal route. The SFPD has reportedly had help from Apple, which loaned a collection of iPhones that were then sold by undercover police officers.
