WASHINGTON – Two weeks after a federal court halted some detainer requests from Immigration and Customs Enforcement, Arizona law enforcement agencies say they are still doing business with the agency as usual. But the ruling exempts states where state law allowed local officials to hold immigrants, and Arizona is one of those states. For Santa Cruz County Sheriff Tony Estrada, that means turning people over to Border Patrol, but only if federal authorities can come immediately and pick them up. He said “the vast majority” of county sheriffs see the benefit of working with ICE and honoring its requests. “It takes away one tool” ICE has historically used, Reyes said, “but it doesn’t take away the toolbox.”
