“The FBI has repeatedly grossly exaggerated the problems it encountered due to encrypted cell phones, the Washington Post reported Tuesday. The bureau had claimed that its investigators were locked out of nearly 7,800 devices linked to criminal activity last year, when the number of devices is probably between 1,000 and 2,000, the Post reported. FBI director Christopher Wray cited the figure in reference to the Going Dark problem, in which law enforcement officials have the legal authority but not the technical ability to access encrypted communications.”
