This is brilliant, a zoomable map of the USA that shows which surveillance technologies are being used in each city.

It shows:
- body-worn cameras
- police drones
- automated license plate readers
- partnership with Amazon’s Ring
- face recognition
- surveillance cameras
- predictive policing
- gunshot detection
- cell-site simulators (like Stingray, for intercepting calls illegally)
The data is from less than a third of police departments, from the research of many students. It is not comprehensive, but an indicator of just how many ways you are being watched.
