>There is zero privacy in public spaces You've agreed that this fact does not preclude uncomfortable scenarios, even for yourself. So, the discussion is about where people fall in their comfort. I would sum up my response to the rest of your comment by noting the difference between individual citizens recording as they please, and a state-operated, always-on surveillance network, with the capacity to surveil every citizen outside of their homes. It's worth noting here that the government famously faces stricter constitutional limits than do citizens. The inefficiency you decry is what others value, as it protects privacy and constrains state power. There's long been a trade-off between efficiency and rights, which much of our legal system seeks to balance—as enshrined in various amendments. Abuse of the frankly violative sort outlined in this article is but one concern, and likely cannot be properly contained in any case—particularly absent the requirement for warrants. This is precisely the reason warrants exist. We don't merely trust law enforcement to abide by its own "rules". So, the larger point is that the very existence of state-operated surveillance networks is considered an intrusive form of abuse by many. One that uses previously unimaginable technology to circumvent the spirit of the Fourth Amendment, which consistency tells us would have otherwise explicitly protected us from such abuse.
