In September, both Apple and Google announced plans to encrypt information on iOS and Android devices by default. Almost immediately, there was a collective freakout by law enforcement types. But, try as they might, these law enforcement folks couldn't paint any realistic scenario of where this would be a serious problem. Sure, they conjured up scenarios, but upon inspection they pretty much all fell apart. Instead, what was clear was that encryption could protect users from people copying information off of phones without permission, and, in fact, the FBI itself recommends you encrypt the data on your phone.
But it didn't stop FBI director James Comey from ignoring the advice of his own agency and pushing for a new law that would create back doors (he called them front doors, but when asked to explain the difference, he admitted that he wasn't "smart enough" to understand the distinction) in such encryption.
So, now, of course, the FBI/DOJ gets to go up to Congress and tell them scary stories about just how necessary breaking encryption would be. And it's being done in total secrecy, because if it was done in public, experts might debunk the claims, like they've done with basically all of the scenarios provided in public to date.
FBI and Justice Department officials met with House staffers this week for a classified briefing on how encryption is hurting police investigations, according to staffers familiar with the meeting. The briefing included Democratic and Republican aides for the House Judiciary and Intelligence Committees, the staffers said. The meeting was held in a classified room, and aides are forbidden from revealing what was discussed.
It's almost guaranteed that someone will introduce some legislation, written primarily by the FBI, pushing for this (such a bill is almost certainly already sitting in some DOJ bureaucrat's desk drawer, so they just need to dot some i's, cross some t's and come up with a silly acronym name for the bill). So far, many in Congress have been outspoken against such a law, but never underestimate the ability of the FBI to mislead Congress with some FUD, leading to all sorts of scare stories about how we need this or we're all going to die.
