Yes these are legitimate concerns.
The use of technology, used for the wrong reasons, is a threat to all of our civil liberties.
Let’s hope some legal safeguards can be established. Offhand I don’t know how such safeguards would function. But I recall a case where someone in law enforcement was using these cameras to stalk his ex girlfriend. Clearly a misuse of the technology.
Require all live camera feeds and video archives to open to public access at no cost.
