ICE, DHS, and the Border Patrol precursors have historically treated native peoples with some of the most cruelty. This goes straight back to Bush, Reagan, even Eisenhower (Operation Wetback swept up a ton of First Nations people in the southern border states).
Really puts the exclamation point on how much of a lie "Immigration Enforcement" is as public policy. It's ethnic cleansing and always has been. Anyone defending ICE is defending white supremacy.
