Swear to god, ICE could just announce they're leaving a city but not leave and the media will just stop covering that city completely even though ICE never left.
It's what ICE and the media did with LA and they're doing it with Minneapolis too

Bipartisan Senate talks aimed at reining in President Trump’s immigration crackdown appeared to sputter on Thursday before they had even started, raising the risk of a shutdown of the Department of Homeland Security in a little over a week.

Now we must make noise for 7 year old Diana Crespo.
Her parents were taking her for emergency medical care when ICE grabbed them, and she’s rotting in the camp sick and exposed to measles.
