I almost completely agree with you here. But it is striking that they didn't need to create any new agencies to do this. All the parts of it were in place. They were in place already for trump to use the first time, and they were still in place when he got back into power.

Due process and transparency on border & immigration interactions has been alarmingly bad for a long time now. Has this never happened before, hidden inside this apparatus? I'm not confident of that. This is certainly different in its scale and ferocity. But I see where they are coming from too.
