I think it's about some memo referring to home raids without warrants would be a constitution violation if it's true. A memo or email I don't think is enough proof on its own to claim it has actually been done though. I also think they want someone to sue so they can rule that illegals don't have constitution protections.
Someone will embrace their civil liberties and blow away the illegal home invaders. There is endless precedence for it even with LEOs. Castle Doctrine an axiom of Western law. We already seeing former gun snatching crowd 180 and roll around protests strapped.
