(No, I'm not an immigrant nor a POC, but I suppose that I AM an "uppity liberal feminist US Citizen defender of the Constitution" so, who knows?.
If they come to my area of Colorado, I will have signs printed up to the effect that a judicial warrant (NOT administrative) is required for entry or discussion (beyond a closed door session. with home-owner/residents at my home address. A reminder NOT to open the door even a crack because once they stick a boot in the door, you can no longer shut the door else you will be accused/charged with assault. Make sure everyone living or visiting your home know NOT TO OPEN THE DOOR TO ICE WITHOUT A JUDICIAL WARRANT. Show your family members how to tell the difference from the samples available online.
Remember, if they stop you in your car, you can't refuse to show license/registration as you would for a
police officer, but answer no questions as to where you are going or coming from or on any other topic. You don't have to provide explanations. Merely politely state you will not be answering questions. You may WANT TO, thinking the questions posed are "innocuous," but just don't. They may not be. They can make you get out of the car and if they DO, lock the door (if you have electronic locks) as soon as you exit the car so there is no question that you have NOT approved a search. If they ask you to unlock the car, state that you will require a judicial warrant and do NOT consent to a search (no, of course you have nothing for them to find, but don't take a chance at their "planting" something). Besides their request is not legally required sans warrant. Oh, and if asked to step out of the car, your passengers will have to do so too--regardless. As we have seen for months, use your cell phone or dash camera to record the encounter. If you are in a state where ACLU allows for recordings to be automatically uploaded to their secured website, do so. But, disable the fingerprint or facial recognition on your cellphone so that they can not get past the need for a court order for your pin number.
Yeah, the legalities are numerous and I never thought any of us would have to consider the minute-by-minute need to take these precautions, but we are living in a very different world now.
