Attorney general’s earlier service, telecom experience shaped his views; some bureau officials were stunned by his rebuke of Apple over Pensacola shooter’s iPhones

WASHINGTONWhen Attorney General
William Barr
returned to the Justice Department last year, law-enforcement officials briefed him on how encryption and other digital-security measures were hindering investigations into everything from child sex abuse to terrorism.Mr. Barr was surprised and puzzled, according to people familiar with the meeting. The government was struggling with similar problems when he first served as attorney general nearly 30 years ago, he told advisers. Why had they not been solved?
With a series of speeches, a sharply worded plea to
Facebook Inc.
Chief Executive
Mark Zuckerberg
and, now, a direct challenge to
Apple Inc.,
Mr. Barr has intensified a long-running fight between law enforcement and technology companies over encrypted communications, potentially setting up a showdown with Silicon Valley. Some agents at the Federal Bureau of Investigation also worry his forceful approach could sour valuable relationships they have fostered with technology companies.
Mr. Barr is disturbed not only by the potential harm that encryption technologies can cause law-enforcement investigations but also by what he sees as tech companies ability to essentially defy court orders, people close to him said.
He views the current conflict as similar to one that was emerging when he led the Justice Department in the early 1990s, they said, when law enforcements wiretapping efforts were disrupted by newly emerging digital technology.
Some within the department have praised Mr. Barr, who is also a former top telecom lawyer, for prioritizing the issue and calling on Apple to help the government unlock two iPhones belonging to a Saudi aviation student who killed three people at a Navy base in Pensacola, Fla. He said authorities had secured a court order within a day of the Dec. 6 shooting allowing them to search the phones but hadnt received substantial help from the technology giant.
An Apple spokesperson disputed that characterization, saying the companys responses to their many requests since the attack have been timely, thorough and are ongoing.
We dont want to get into a world where we have to spend months and even years exhausting efforts when lives are in the balance, Mr. Barr said at a news conference on Monday. We should be able to get in once we have a warrant that establishes that criminal activity is probably under way.
The FBI said its technical experts agreed that further outreach to Apple was needed after efforts to access the phones were unsuccessful. Mr. Barr and FBI Director
Christopher Wray
have been publicly in lockstep. FBI Deputy Director
David Bowdich,
who joined the attorney general on Monday, said he wanted to echo Mr. Barrs points about law enforcements struggles with encryption. But notably, Mr. Bowdich also highlighted the FBIs partnerships with tech companies.
Some senior FBI officials say privately they are worried that Mr. Barrs sharp tone could undermine relationships with technology companies they have worked hard to develop, people familiar with the matter said.
The bureau relies on close partnerships with tech firms in a range of investigations, with companies complying with legal requests for data and troubleshooting technical obstacles that agents may struggle with, current and former officials said. Large tech firms also are frequently victims of crimes with national-security or counterintelligence implications, including cyberattacks and employee espionage, and law-enforcement agencies want those companies to report such issues, the officials said.
What would be the best strategy for Attorney General William Barr to approach tech companies when it comes to encryption? Join the conversation below.
Some FBI officials were stunned by Mr. Barrs rebuke of Apple, the people familiar with the matter said, and believe the Pensacola case is the wrong one to press in the encryption fight, in part because they believed Apple had already provided ample assistance to the probe.
The question for FBI officials is always whether a public spat with a major technology company is worth the cost in terms of time, effort and damage to the FBIs relationship with the tech sector, said former FBI general counsel Jim Baker, who was involved in a high-profile 2016 clash with Apple over a locked phone also belonging to a dead terrorist. The standoff was resolved when a contractor hired by the bureau was able to get into the phone.
Apple, too, was surprised by Mr. Barrs stance and is strategizing about its next steps, including the possibility of a legal fight, according to a person familiar with the matter.
Senior Justice Department officials said they view their push as a necessary step in investigating the Florida terrorist attack. The gunmans locked phones could offer valuable clues about whether he conspired with others overseas, they said.
Mr. Barr became the top lawyer at a big firmGTE, now
Verizon Communications Inc.
in 1994, when Congress passed the Communications Assistance for Law Enforcement Act, requiring telecom companies to enable their services and equipment to comply with law-enforcement surveillance requests. He has said he finds it absurd that tech companies would be exempt from such rules.
Based on his experience in telecom, Mr. Barr said in July, he reserves a heavy dose of skepticism for those who claim that maintaining a mechanism for lawful access would impose an unreasonable burden on tech firms, especially the big ones.
Mr. Barr and other department officials have given little public indication of their next move. The administration has begun discussing ways to solve the problem through legislation, Mr. Barr said.
Administration officials have an ally in Sen.
Lindsey Graham
(R., S.C.), chairman of the Senate Judiciary Committee.
Youre going to find a way to do this or were going to do this for you, Mr. Graham told tech companies at a hearing late last year.
While lawmakers of both parties have been openly critical of Apple, there is little indication of broad bipartisan interest in mandating government access to encrypted communications.
Apple CEO
Tim Cook
has recently amplified the companys defense of privacy, touting it in ads. The publics understanding of privacy and encryption issues has deepened, too, in the wake of hacking scandals. And any court challenge the Justice Department makes to Apples policies risks a decision that makes it even harder for the department to gain access to phones.
Theres a risk that you wind up with a situation worse than the status quo, said Michael Chertoff, a former secretary of the Department of Homeland Security and co-founder of a strategic advisory firm that has worked with tech companies, including Apple, on security issues.
Mr. Chertoff said a court ruling against the Justice Department could limit access to widely available forensic tools that allow investigators to get into phones in some situations, for instance. Its not clear to me why this fight is advantageous to anybody, he said.
