IIRC (and please correct me if I’m wrong) the only criminals in Tent City are convicted felons who have been sentenced to serve more than a year in prison. “Short timers”, like people convicted of misdemeanors or people awaiting trial who can’t afford to post bail, are housed in a conventional jail.
We went in there to search Tent City back around 1995. One of the things we had to do was search all the inmates who were returning from their day jobs to spend the night in the tents. Those were probably DUI-type folks, those who were not violent or hardcore. The really bad people are housed inside the hard jail cells.
Arizona is a very Red state. Every ballot measure that makes it hard on illegal aliens always passes with overwhelming support from voters. ACORN will get no foothold here.
