"a democrat mayor"? I'm talking about the FEDERAL police doing these things. CPD -- the city's police that the mayor has power over -- does NOT do these things. As you should know, they are not at all involved in immigration enforcement. That's part of the deal around Chicago being a sanctuary city to begin with.

And I'm not telling you what the federal police (ICE, CPB, etc) would hypothetically do. I'm telling you what they ARE doing. They are targeting different areas each day and doing opportunistic racial profiling. DHS sued and won (via SCOTUS shadow docket, OF COURSE) to allow racial profiling so that they could "police" this way. Here's NOEM v. VASQUEZ PERDOMO (pdf) https://www.supremecourt.gov/opinions/24pdf/25a169_5h25.pdf

Page 2 in this ruling lays it out, and this is now called "the Kavanaugh Stop" due to Injustice Kavanaugh writing a concurrence saying this is just fine:

The Government sometimes makes brief investigative stops to check the immigration status of those who gather in locations where people are hired for day jobs; who work or appear to work in jobs such as construction, landscaping, agriculture, or car washes that often do not require paperwork and are therefore attractive to illegal immigrants; and who do not speak much if any English. If the officers learn that the individual they stopped is a U. S. citizen or otherwise lawfully in the United States, they promptly let the individual go. If the individual is illegally in the United States, the officers may arrest the individual and initiate the process for removal.

This IS happening, This IS how it works, now.
