The phone companies are NOT willing. They’re the subject of questionable FISA warrants and even more questionable national security letters.
Now they have grounds to demand actual warrants that don’t come from politically biased secret courts or notoriously biased Deep State operatives.
FISA warrants are still warrants, this case wont have any impact on the concerns you raised.
A FISA warrant is still a warrant, nothing has changed at all with those. That is foreign intelligence anyway, a bank robber or Joe civilian doesn’t even fall anywhere near their preview.
This is just the police demanding to see his stored information a wireless company have on an individual, and they have been capitulating and giving them that data without a fight.
Now if they do that they can be sued by the person who they harmed, whether or not they’re guilty of a crime if the police don’t get a search warrant first.
