A new lawsuit alleges that the Department of Homeland Security (DHS) is using artificial intelligence to identify bystanders who are recording federal immigration enforcement operations and then adding those people to a secret database.

Two women from Maine filed the lawsuit and claim that federal agents threatened to add them to a database of domestic terrorists because they were legally recording the agents.

In a video included in the lawsuit, a woman behind the camera tells a federal immigration agent that “it’s not illegal to record” and questions why he is apparently documenting her information. The agent responds by saying “we have a nice little database. And now you’re considered a domestic terrorist, so have fun with that.”
