I don't understand what's the beef here. Those families don't just get a knock on the door and get picked up and shipped back.
1. They have to go to court. That takes years.
2. They are getting deported because they didn't show up to court, therefore the ruling was ordered in absentia.
3. Once the ruling is ordered they are deported.
4. They don't deport you without seeing a judge, unless you illegally reentered again or didn't show up to court...

UNLIKE DACA
Most of us never been to court, so when they strip DACA they have to put all of us through court procedures. Serving all DACA recipients with court orders would be pretty darn hard, not to talk about man power, costs, and time it would take, is highly unlikely. When DACA gets taken down, most of us will be grandfathered in until they figure out what they are going to do with us or immigration in general.
