I just saw this article that partly answers your question. Sounds like they already know who to arrest. Just a matter of going to their homes or workplace and rounding them up.
Immigration officers likely have already obtained arrest warrants for the targeted individuals in Chicago that would give them grounds to make arrests or searches, whether or not the resident opens the door. Officers should take additional steps if they detain someone without a warrant in place, but historically haven’t done so in big immigration roundups, Zwick said.
So BabyBoobs "thinks" all those “bad hombres” (not the "good" undocumented immigrants) are going to be sitting in their known locations after hearing ahead of time that ICE is coming for them???
Let’s see how effective a MASSIVE raid on those “bad hombres” is when they are given a heads up like the one President Musk (and DonOld) just gave them.
My prediction???
A fuckton of wasted money and resources, with little to show for it except a PR stunt.
Newsflash:
Just like our foreign adversaries / competitors figured out how to play / beat DonOld’s game of TELEGRAPHED one dimensional tic tac toe moves to avoid tariffs, etc, the criminal immigrant gang leaders / “bad hombres” are going to figure out how to avoid DonOld’s TELEGRAPHED mass roundups. (The law abiding undocumented immigrants / “good hombres” might not be able to dodge the roundups as effectively.)
Hope that ^ helps.
