What you do on public roads is public.
The idea that law enforcement tapping into existing law enforcement knowledge constitutes as a search of "persons, houses, papers, and effects" does not logically follow for me. It is a search of law enforcements own property.
It’s public, but that does not necessarily imply that I will be surveilled at all times by the state while out in public.
> It is a search of law enforcements own property
The wording here seems problematic. Why is law enforcement entitled to this degree of access to public surveillance as their "property"? That word strongly implies it is theirs to do with as they wish - I don't see how that would be a desirable state of affairs.
Omniscience outside private property is “existing law enforcement knowledge”?
> It is a search of law enforcements own property.
The roads are not law enforcement's property and my private car on a public road is private property that requires a warrant to search. These things should be totally banned, but even your argument is wrong since Flocks don't mask just the road, they record everything in their field of view.
