The inability of law enforcement authorities to access data from electronic devices due to powerful encryption is an "urgent public safety issue," FBI Director Christopher Wray said on Tuesday in remarks that sought to renew a contentious debate over privacy and security. From a report: The FBI was unable to access data from nearly 7,800 devices in the fiscal year that ended Sept. 30 with technical tools despite possessing proper legal authority to pry them open, a growing figure that impacts every area of the agency's work, Wray said during a speech at a cyber security conference in New York. "This is an urgent public safety issue," Wray added, while saying that a solution is "not so clear cut."
