Dear Senator Murray

I am writing as a constituent to urge immediate oversight of ICE’s use of AI-driven surveillance tools, data brokers, and cell-site simulators that violate privacy and constitutional protections.

ICE’s reported use of tools such as Weblock and Tangles allows the agency to purchase location data, scrape social media, build AI-generated personal profiles, and track individuals’ movements and routines—often without warrants or consent. These tools are then used to narrow geographic targets for physical enforcement actions.

ICE’s use of cell-site simulators (Stingrays) is especially alarming. These devices impersonate cell towers, forcing nearby phones to connect and exposing personal data of everyone in range, including U.S. citizens and bystanders. This constitutes mass surveillance and raises serious Fourth Amendment concerns.

This unchecked use of technology threatens privacy, safety, and civil liberties. I urge you to demand transparency, prohibit warrantless data purchases, and require strict judicial oversight of all surveillance tools used by ICE.

I urge you to:

• 
  Demand accountability from DHS and ICE regarding their data collection and sharing policies.
• 
  Oppose any appropriations that fund increased surveillance technology or data-sharing capabilities for ICE without strict oversight.
• 
  Support legislation that protects the privacy of all residents and ensures ICE operates transparently.

Privacy is a constitutional right, not an optional safeguard. I ask you to act.

Sincerely,

Washington constituents
