During a military-style raid on a building in Chicago’s South Shore, one resident heard a knock on his door.
It wasn’t the feds — it was a mom and her 7-year-old daughter, pleading for help.

I've said this before, but I feel pretty strongly that the building of concentration camps - and now, the inevitable disappearance of 1,800 people from those camps - is the biggest story in American public health right now that isn't being treated like one
More than 1800 detainees are missing after the closure of Alligator Alcatraz. Their families and lawyers can’t find them and they’ve vanished from the ICE database. Feels like this should be a much bigger story www.miamiherald.com/news/local/i...
Hundreds of Alligator Alcatraz detainees drop off the grid after leaving site
As of the end of August, the whereabouts of two-thirds of more than 1,800 men detained at Alligator Alcatraz during the month of July could not be determined by the Miami Herald.
