The CATO Institute reports that data from ICE/DHS shows that one in five ICE arrests are Latinos on the street with no criminal past and no removal order. This means, according to the article, that these people have likely been profiled and randomly picked up instead of their arrests being the result of careful research that would prioritize harmful actors.
The report shows that IDs are questioned and many citizens have been detained by ICE. And that after a federal district court told ICE that they were not allowed to profile potential detainees (on July 11th), the street arrests (where profiling occurred) dropped. That federal district court decision was upheld in the 5th Circuit court of Appeals in August.
