But it says nothing as to what the Government can do when they do have a warrant. If they get a judge to sign one, provided the warrant meets the particularity requirement, they can go obtain what they need.
As far as Flock is concerned, it’s mainly a process thing. Right now they might be able to share their data with law enforcement without a warrant. If the law changes, the data will still be there, except henceforth, law enforcement will need to obtain a warrant before getting it. So there will be that safety mechanism, although security vulnerabilities could make it available to hackers.
The bigger question in my mind is “should such systems even exist in free states,” but as written, our Constitution doesn’t explicitly forbid them.
There should not be any system that allows a person to be continuously tracked at all times short of as a consequence of criminal activity with a judge signing off on it.
It's so basic that a 3rd grader gets it.
(which... we should, if we have the data to do it, why not actually enforce traffic laws?)
