The law (thankfully) is not some hard coded machine that follows cold logic ignoring all context. (Good) judges are able to look at changes in context and recognize that the underlying factors have shifted and so change rulings.
You are entitled to privacy even for certain public situations. Even if you can see through a window, the government can't go training telescopes inside your home without a warrant. It's an active battle for things like location data.
You would think with AI we could track all guns and bullets to crimes eventually.
Not sure how that would be achieved since you can make your own guns and bullets in the majority of states.
Funny thing about that which could also apply to data/AI/etc, is that I understand the ATF is ignoring that law anyways.
tl;dr: I see it as the difference between using search tools to monitor for potential suspects vs search tools to implicate already identified suspects.
