I live in Sausalito just north of SF. We have a few cameras on the way into town. Seeing this map actually makes me feel safer. Sure there are hypothetical privacy issues, but for me they're easily outweighed by safety. I don't really get the issue. Ideally this information would be available to law enforcement, but would require a warrant. Is the problem that they can access all of this data without a warrant now?
Based on comments here, I'm thinking that a lot of the Flock opposition is affiliated with the anti-ICE movements. Flock seems to be viewed here as a tool to persecute and hunt down law-abiding government enemies, potentially bypassing civil liberties.
I don't deny that Flock systems could and may have been used in that manner, but that doesn't seem to be its main purpose or use. Presently I'm seeing Flock as a net win for most law abiding persons, and I believe that its use should and can be highly restricted and monitored as a tool to make the country safer. No reason to throw the baby out with the bath water
