The headline says he called ICE, but the only thing I see in the article is he told the Dems he did.
I hope he didn't actually call, as fun as it would be. I don't think there's probable cause to check immigration status soley on attendance of a protest. If he did call it would play into the left's narrative of what we want to accomplish.
OTOH, my first thought on the LA article was ICE should call in a couple hundred extra agents and see if the neighbors really do want to interfere with official acts, which would, IMO IANAL, be grounds to arrest them and check their status, too.
