More than 2,000 US law enforcement agencies have access to facial recognition systems, according to Georgetown Law’s Center on Privacy and Technology.

These agencies use facial recognition technology to identify people in public spaces without public announcement, vote, or community conversation. This means that people may be scanned and matched against a database without their knowledge or consent.

The technology is being used in cities across the US, with no clear oversight or regulation. This has raised serious concerns about civil liberties and the potential for abuse.
