What about the prison tent camp the Sheriff in AZ put up a few years ago ... now, that did not seem to be a very pleasant place to hang out.
Tents might work if you have ankle bracelets. But they don't provide much protection. God knows what the more thuggish types would do to the ones who came to work. They should be shackled for their own safety, I guess. But the left would complain about marks on the wrists. That's how wimpy America has gotten.
Sad FReegards....
