U.S. Officials Hopeful About Unlocking Shooter's iPhone

U.S. officials said that they are hopeful they will be able to unlock an iPhone used by one of the San Bernardino shooters without help from Apple Inc, but said the national debate over privacy and encryption must still be resolved. Attorney General Loretta Lynch told a news conference that the Justice Department is "trying to exhaust all investigative tools" to gain information on the San Bernardino attackers, including by using techniques offered by third parties.
