Barr attacks encryption as security risk

Attorney General William Barr in lengthy remarks on Tuesday said he believes encryption is allowing “criminals to operate with impunity” in the digital world, reopening a bitter fight between the U.S. government and tech industry over whether law enforcement should be given special access to encrypted messages.

Barr came out strongly against completely encrypted messaging, alleging that it has prevented U.S. law enforcement from tracking down criminals at the helm of drug cartels and even some responsible for murders.

“The [cost of encryption is] ultimately measured in a mounting number of victims — men, women and children who are the victims of crimes, crimes that could have been prevented if law enforcement had been given lawful access to encrypted evidence,” Barr told the crowd at a cybersecurity conference in New York City.

A new round in an old debate: The country’s top law enforcement agencies for years have warned that encrypted communications and data could pose national security risks, considering investigators cannot tap into those messages between potential criminals or terrorists even with a court order.

Encryption converts messages and data into code to prevent unauthorized access. Messaging services like WhatsApp and Signal tout end-to-end encryption, a system of communication where only the senders can read the messages.

The tech industry and cyber experts have defended encryption as a necessary privacy measure that offers a method of protecting communications from outside intrusion and hacking. Proponents of encryption have said creating “backdoor” access for law enforcement would undermine the security of messaging systems.

“Making our virtual world more secure should not come at the expense of making us more vulnerable in the real world,” Barr said on Tuesday. “But unfortunately, this is where we appear to be headed.”
