Your comment isn't totally true in the narrow sense that it's not being done domestically by the USG specifically (at least at the time I was reading about it).

The primary domestic use was by the Baltimore police department and it was supplied by an individual billionaire interested in funding the project.

Interesting fact in that book was that the initial spark for the project was someone in government watching Enemy of the State in the 90s and thinking "we should be building this". Somewhat comically the guy who worked on the camera effects in the movie also has a defense company and was asked to help build the real thing.

This wouldn’t make a difference.

Read Eyes In The Sky or just generally about WAMI (wide area motion imagery): https://www.amazon.com/Eyes-Sky-Secret-Gorgon-Stare/dp/05449....

There will have to be legislation around use and access in order to have any real protection.

Bizarrely enemy of the state directly provided the inspiration.
