Surveillance infrastructure expanding, civil liberties catching up slowly

A leak of San Francisco Police Department drone footage surfaced on HN, and the discussion connected it to a broader pattern of urban surveillance expansion. Commenters noted that European GDPR hasn't actually stopped surveillance proliferation, and that this is becoming a defining civil liberties fight globally. One commenter referenced a Bloomberg piece about a company running Cessnas with high-resolution cameras over cities for hours, stitching footage into persistent surveillance records.

The pattern: law enforcement surveillance capability is scaling faster than legal frameworks governing it. Drones, aerial photography, and networked cameras are commodity technology now, which means the barrier to deploying city-scale surveillance is low and falling. The leak itself suggests internal controls are also weak.

For builders, the relevant tension is that many of the underlying technologies (computer vision, edge inference, drone hardware) are neutral, and the same capabilities that worry civil libertarians are being sold as public safety infrastructure.
