The No. 2 official at the Justice Department recently warned top Apple executives that stronger encryption protections added to iPhones would lead to a horrific tragedy, such as a child dying, because police couldn't access a suspect's device, The Wall Street Journal reported Wednesday.

The beefed up protections, Apple recently disclosed, mean that even when company officials are served with a court order, they will be unable to retrieve potentially crucial evidence such as photos, messages, or contacts stored on iPhones and iPads. Instead, the data can be accessed only by people who know the passcode that serves as the encryption key.

Justice Department officials wasted no time objecting to the changes and used the scenario of a child being kidnapped and murdered to drive home their claim that Apple was "marketing to criminals." According to the WSJ, Justice Department officials including Deputy Attorney General James Cole met with Apple General Counsel Bruce Sewell and two other company employees on October 1. Reporters Devlin Barrett, Danny Yadron, and Daisuke Wakabayashi gave the following account, which they attributed to the recollections of people who attended.

In his fourth-floor conference room, Mr. Cole told the Apple officials they were marketing to criminals. At one point, he read aloud from a printout of Apple’s announcement, quoting a section in which the company said that under the new system Apple couldn’t cooperate with a court order to retrieve data from a phone even if it wanted to. Mr. Cole offered the Apple team a gruesome prediction: At some future date, a child will die, and police will say they would have been able to rescue the child, or capture the killer, if only they could have looked inside a certain phone. His statements reflected concern within the FBI that a careful criminal can shield much activity from police surveillance by minimizing use of cellphone towers and not backing up data. The Apple representatives viewed Mr. Cole’s suggestion as inflammatory and inaccurate. Police have other ways to get information, they said, including call logs and location information from cellphone carriers. In addition, many users store copies of a phone’s data elsewhere. During the hour-long meeting, Mr. Sewell said Apple wasn’t marketing to criminals, but to ordinary consumers who store growing amounts of data about themselves on smartphones and are increasingly suspicious of tech companies. Many of those customers are outside the US, the Apple representatives said, where phone users want to shield information from governments that are less respectful of individual rights. If the government wants more information from Apple, the company representatives said, it should change the law to require all companies that handle communications to provide a means for law enforcement to access the communications. Mr. Cole predicted that would happen, after the death of a child or similar event.

Prior to changes introduced in iOS 8, Apple had the means to pull data off of a locked phone, and according to the WSJ, the company helped police do just that when it was served with a valid court order. Under the latest iOS version, the data can be recovered only by knowing the passcode. Passcodes that are sufficiently long and complex make it infeasible for Apple or anyone else to crack. US Attorney General Eric Holder recently said it was "worrisome" that tech companies were adding default encryption to consumer electronics. Apple CEO Tim Cook recently pushed back at a WSJ conference, saying "Look, if law enforcement wants something, they should go to the user and get it. It’s not for me to do that."
