In theory, a system which scans/records/monitors every private citizen in a public space is:
(a) technically constitutionally acceptable, because individuals in a public space have fewer expectations of privacy.
(b) hard to argue against because we are already on camera most of the day - whether we're on a security cctv at the store, or behind the dashcam of another motorist, we know (even if we deny/don't think about it) that we're being watched.
the troubling part is when that data is mishandled, misused, or exploited. how do we make sure that pandora's security box doesn't turn into pandora's blackmail box?
open source. public access. full disclosure.
re-write the rules about public privacy?
