I wonder what his repeat statistics are in comparison to other places that run taxpayer funded country clubs.
But the factual answer to your question is that, according to an ASU professer who studied that exact thing, "there was no significant difference in recidivism observed between those offenders released in 1989-1990 and those released in 1994-1995." (Arpaio's first term as sherriff started in 1992.) That's on top of the fact that arrests for actual serious crimes (that is, other than the crime of "being Hispanic") are plummeting, and the FBI claims a 70% increase in violent crimes and a 166% increase in homicides for this clown's county over the past 5 years. Given how absolutely horrible a job he's doing at actually enforcing the laws, it really is mind-boggling how many people buy into his PR stunts and keep relecting him.
