If you remove the technology that they wouldn’t understand, the founders wouldn’t consider Flock to be some absurd concept: a sheriff asking a night watchman standing on the road into town “did you see George go by riding Samuel’s horse?”
It’s a reasonable question, it’s a public road, and it doesn’t violate George’s privacy in his person, home, papers, or belongings.
How about "Give me an instant heat map of all of George's movements the past year across all 13 states. With a particular focus on parking up near any and all brothels"
Do you think George parking his horse/car in a public parking lot outside a brothel should confer an expectation of privacy?
Can a bank or ATM miles away have a security camera, just on the off-chance that George stops to withdraw cash for said brothel?
Can police not stake out the brothel to gather evidence of prostitution because all the patrons have an expectation of privacy?
IE, is it ever acceptable to be noticed in public just because you may be doing something unsavory?
It's not the individual threads, it's the tapestry made whole.
That's a pretty nebulous answer. Just to help solidify my understanding of your position, can the government ever operate a camera recording a public roadway?
