Most local law enforcement don't want anything to do with this. 

Tucson, Ariz., Police Chief Chris Magnus: “Entangling local policing with additional immigration enforcement responsibilities would seriously compromise our ability to maintain the trust and support of our diverse community.”

Yuma County, Ariz., Sheriff Leon Wilmot: "I would not use [county] taxpayer money to perform an immigration function ... Because I don’t have the manpower to be doing all that."

“Immigration is a federal issue,” Cochise County Sheriff Mark Dannels said. “Public safety when it comes to state law is my issue."
