If you need to explain to non-technical friends and family exactly why this is a terrible idea, CGP Grey offers an easily digestible 5-minute primer: https://www.youtube.com/watch?v=VPBH1eW28mo

Computers either have unbreakable locks, or no locks whatsoever. There's no stable middle ground.

No one can force your to share information. Let's say your PIN code is 1324, and you suffer from stress induced transposia (just made that up). Every time you are asked to say or share your PIN code, you get stresses & use 1234, even though you meant to use 1324. There's no way make you say the correct PIN code. In a more realistic example, what are you going to do to someone who simply forgot their PIN code?

> In deciding against Rawls, the court of appeals found that the constitutional rights against being compelled to testify against oneself were not being breached. That's because the appeals court, like the police, agreed that the presence of XXXXXXXXXX on his drives was a "foregone conclusion." The Fifth Amendment, at its most basic level, protects suspects from being forced to disclose incriminating evidence. In this instance, however, the authorities said they already know there's XXXXXXXXXX on the drives, so Rawls' constitutional rights aren't compromised.

> ""Forensic examination also disclosed that Doe [Rawls] had downloaded thousands of files known by their "hash" values to be XXXXXXXXXX. The files, however, were not on the Mac Pro, but instead had been stored on the encrypted external hard drives. Accordingly, the files themselves could not be accessed.""

A good guess can figure out what I've redacted.

> unbreakable locks

Replace that with "locks that have yet to be broken", and I agree.

In the last crypto wars in the 90s and competent scientific explanations of the dilemma between trustworthy and backdoored didn't register with people who think in political terms either.

The government side of this is rhetorically, "we can imprison and kill engineers until one of you delivers us a flying pig, whether you still say that's impossible is your call." Some engineer is going to figure out how to meet their requirements. Pigs themselves can't fly per se, but when you get to discussing how far, in what direction, for how long, under what power, and the consequences of doing nothing, even flying pigs become a solvable problem. A technologist will say, "that's horrible, unethical, and wrong, you just ran those pigs off a cliff." Everyone else looks at the politicians and the guys with the guns and says, "See? Flying pigs." They also probably push that technologist over the cliff as well.

This is why they call politics the art of the possible.

What Barr is saying is that he plans to make tech companies accountable for his problems in justice. This kind of irrational posturing is probably a bargaining gambit on other regulatory areas or just an empty signal to rank and file law enforcement that the whitehouse and AG are on their sides.

Look, same applies for example to 2nd amendment. But people find it plausible and vote for more gun control.

Not even close to the same thing.

It's pretty close. For a while crypto was classified as munition and placed under very strict export control in the United States.

"[...]The cost of encryption, he said, is measured in "victims" who might have been saved from crime if law enforcement had been able to lawfully intercept communications earlier.[...]"

Yes, one can measure the cost of encryption like this, just like you can measure the cost of lax gun controls or automobile traffic by their fatalities (= negative costs). But you also measure the cost of encryption and lax gun controls and automobile traffic by their benefits (positive costs). If the balance is sufficiently in the positive, the negative costs might get accepted. There is no logical point, to only reason from one side of the calculation.

I never heard Barr say:

"The cost of privacy is measured in 'victims' who might have been saved from crime if law enforcement had put an officer in every bedroom throughout the country."

"The cost of lax gun controls is measured in dead pupils who might have been saved from death if legislation had passed stricter gun control laws."

> The FBI ended up in possession of the shooter's iPhone during the investigation but was unable to unlock the device, as the attacker had been killed and therefore could not be compelled to share his PIN. Is it not the case that he couldn't be legally compelled to share his PIN even if he were alive?

You probably cannot be compelled to say what your password is,but you can be compelled to place your finger on the fingerprint scanner, provide retna scans, and provide other biometric data to unlock encryption. The difference being that you cannot be compelled to reveal information you have in your own mind. The rest of your body, however, is fair game.
