WASHINGTON (Reuters) - Unlocking an iPhone used by one of the San Bernardino shooters would leave hundreds of millions of Apple Inc (AAPL.O) device owners vulnerable to cybercriminals and other hackers, the company’s top lawyer is expected to tell U.S. lawmakers on Tuesday. In written testimony to the U.S. House of Representatives Judiciary Committee released on Monday, Apple General Counsel Bruce Sewell reiterated the tech giant’s stance that the FBI’s request to help access the phone “would set a dangerous precedent for government intrusion on the privacy and safety of its citizens.”
