“We already don’t know who is grabbing us, whether it’s ICE or whether it’s people who disguise themselves as ICE,” Yackson says in Spanish. “With the National Guard, it’s going to be even harder, scarier.”

In several cities across the country facing National Guard deployments, NPR has heard similar sentiment.

“The government isn’t exactly doing a great job of proactively delineating this person is National Guard who isn’t allowed to arrest immigrants, and this person is an ICE agent or an FBI agent who is,” says Dara Lind a senior fellow at the American Immigration Council, noting that many times federal agents are in military-style gear, or masked, or not clearly marked.

She says this makes it hard to look at patrols on the street and figure out who is legally authorized to engage in law enforcement activities or not.
