The issue is that times are changing. "Worked fine for decades" doesn't apply to the Ring Doorbell or Flock. Or that authorities exactly want to have all footage in the one place, from train stations too.

Modern computers allow for scaling of capabilities that are only tolerable at all when limited in number.

IE the capability to track an individual's every movement is tolerable if it is limited in number, has oversight, and only used by appropriate authorities against bad people that everyone can agree are bad.

But being able to track minority groups en masse as modern systems are capable of is clearly an issue.

I see your parameters to the above questions as mostly reasonable although I'd rather not have the cameras everywhere in the first place. But do you think even your reasonable seeming desires are being adhered to?

I don't.
