I hear that Sheriff Joe has his Vacancy sign out. Put them in tents out by the Salton sea.
Hey, I live near the Salton Sea. We already had to fight off a Riverside County attempt to build a large county jail at the entry freeway to Palm Springs and the other desert resort cities.
Just the same, I have advocated building state prisons and county jails much farther out in the desert in areas where there was not a single person within 10 miles. Surround it with three sets of razor wire fences, and lots of other detection equipment. Put them in buildings with no AC and have them spend their days moving sand from one place to another and then back again. No TVs, no exercise equipment. I guarantee you that 99% will never return once they are released.
