Its not that hard. Don't let them in.
Put them on a bus, or on a train heading south, and send them back! What’s so difficult about that? Instead, they’re releasing them all and telling them to show up in two weeks for a hearing. Yeah, right. They’ll be there.
WE shouldn’t have to do anything with them beyond dumping them at their embassies and stationing US military around those embassies to make sure no illegal sneaks out the back door.
