> I trust we would take action the moment something gets abused or surveillance overreaches.

The thing about turnkey authoritarian solutions is that once something happens it's likely too late to take action. However there are often alternative solutions that physically constrain the system such that substantial abuse is impossible without time consuming and expensive physical modifications. The traditional speed cameras in the UK for example.

Cameras, AI integrated at the edge, software that can't be updated remotely, the full stack publicly audited, that only output video data when a suspected violent crime is flagged. Something like that might work. I'm not optimistic such a solution would see much support though.

You'd also probably want a policy put in place in advance to quickly pull them down if certain criteria are met. But again, I'm not optimistic about the prospects.
