The Electronic Frontier Foundation's Street-Level Surveillance project is a collaboration between staff attorneys, technologists, and activists to shine light on privacy-invasive police technology, limit how the technologies are used, and hold agencies accountable for their abuse.

If you represent a local organization interested in grassroots advocacy on surveillance issues, please consider joining the Electronic Frontier Alliance. For legal matters, please see our Criminal Defense Resources page or email EFF's intake coordinator at For press inquiries, please email
