The Brennan Center filed public records requests with police departments in Boston, New York City, Los Angeles, Baltimore, and Washington, D.C., seeking information about their use of third-party social media monitoring tools. The resulting documents revealed new information about how these tools are used and the relationships between law enforcement and these third-party vendors.

Below is information on what we know about each of the companies, including their data sources, the tools’ purported capabilities, and publicly available information about the companies’ public-sector clients, as well as relevant documents acquired through the Brennan Center’s public records requests. We will update this resource if we receive additional relevant documents.
