I was thinking the exact same thing —Arpaio tent camps, complete with pink jumpsuits, baloney sandwiches and water for every meal, and chain gang hard labor every day from dawn to dusk. No TV, no workshops, no library, no gym.
If the Feds won’t process them and deport them, it would be cheaper for the AZ budget to keep them in that kind of detention forever than it would to police them and the street crime they cause.
And we have tons of trash left laying around our National Forests down here that the incarcerated illegals could pick up while working on a Sheriff Joe-style chain gang!
