Of course, the only time that kind of stuff gets vigorously challenged is if the defendant has top-notch legal representation. Public defender's typically would rather just plea-bargain it out.
Still, it's great progress for keeping everything above board as much as possible.
For example, if a cop says "I'm pulling this person over because they have a busted tail light", it's hard for them to make a claim that they thought the person could have been some sort of drug kingpin that needed further searching.". Compare this to "I'm pulling this vehicle over because I just saw it leave a known drug house."
The more we can recreate "presence" at a particular time and place when a crime (by an individual or by a LEO), the more information judges and juries will have to deliberate if suspicion was in fact reasonable, and not based on some arbitrary detail like the race of the person being stopped.
Recreating presence makes it so someone no longer has to depend on top-notch legal council to artfully argue why they are innocent. It should bring down the legal costs of both the prosecution and the defense, while achieving greater justice.
It's a lot harder to start a widespread, hard-to-undo abuse of power when you have to ask permission each time you exercise that power. A single abuse of power can be (hypothetically) remedied in court after the fact. Unfortunately, the situation changes when the problem grows to "general warrant" size. At that scale, you tend to need armies, not courts.
So lock your phone immediately. Give remote wipe to a trusted family member if you are truly worried.
I believe the idea is that they can try to disable the lock in order to keep the evidence available for use after getting a warrant.
They don't even need that much at the rate most warrants are sworn out.
in any case, it's good to see this decision. perhaps it's the beginning of the legal system recognizing that electronic data is private information and should be protected.
[edit: to the totally confused. My comment is political satire. And it purposefully misidentified which "source" you were referring to for purposes of bitching about USA law enforcement.]
e.g. "a confidential source" that we saw on here yesterday.
That implies some confidential source was featured on HN yesterday. Linking to that post should do none of those things.
In short, he was saying that we can reliably expect many warrants to have been obtained by law enforcement lying to judges. Based on the information (lies) presented to the judges, they're going to approve the warrant, because they operate on the premise that law enforcement wouldn't lie to them.
