The federal government loves to play this 'it's only civil, not criminal, therefor a loser set of rules apply' to lots of things. Knowing it's an end run around rights people/lawyers/courts have still let them get away with it because they support the final outcome or because it simplifies the process.

And the problem of not allowing other government officials outside of ICE and the executive having access to facilities, paperwork, camera systems. ICE can too easily hide what they are doing. The lack of transparency and oversight is despicable.
