@psoul But that's not how the federal government is set up, so it can't really work that way.
For example, should ICE detain people through programs that weren't properly funded, the detention would not be legal, and so would be extra-governmental. Unauthorized.
Yes, you might say that Trump doesn't care about legalities, and that would fit with his pattern, but when we're talking about extra-governmental detention it would be happening as if he wasn't president anyway, it would just be effectively private citizens abducting people.
It's a very different context.
