The FBI said it would try to help local law enforcement agencies to open locked phones and other devices in an advisory on Friday. “As has been our long-standing policy, the FBI will of course consider any tool that might be helpful to our partners,” the agency told local authorities in a letter, the Wall Street Journal reported. “Please know that we will continue to do everything we can to help you consistent with our legal and policy constraints.’’ . The message was issued in response to a surge in interest from state and local authorities after the FBI was able to unlock an iPhone belonging to one of the San Bernardino shooters without the assistance of Apple.
