Sanctuary cities like Chicago, Philadelphia and L.A. say they won't enforce any deportation orders from a President Trump, despite his threat to yank billions in federal dollars.
Phoenix is not a sanctuary city -- law enforcement here does work with the feds on deporting criminals -- and that probably won't change under Trump.
"This deportation force that everyone is talking about nationally now, has already happened here," said immigration attorney Delia Salvatierra.
Maricopa County would be a model for Trump's proposed round-ups, she said.
Salvatierra laughed off my question about whether the city of Phoenix or other local law enforcement would stand in Trump's way.
"I started to laugh because that is just not in the realm of possibilities," she said.
Not in the state that passed SB 1070 in 2010, at the time the nation's toughest crackdown on illegal immigration.
"Politically I just don't see it," she said. "Legally, yes."
The term "sanctuary city" generally refers to cities that don't cooperate with federal authorities on enforcing immigration law.
Maricopa County and Phoenix law enforcement already work under agreements with U.S. Immigration and Customs Enforcement to check the immigration status of suspects booked at jails. They also alert immigration officials when undocumented convicts are released.
Salvatierra says the agreements could be canceled at any time.
"This is the one area of immigration law that is dependent on the state's willingness to cooperate," she said.
"There is no law in the nation that says local law enforcement must turn over any undocumented individuals to the federal government."
Sheriff Joe Arpaio led the way with the agreements, formally know as "287-g's." His successor, Paul Penzone, was not available to comment about what he might do.
Salvatierra doubts Penzone would change things.
"He has so many things to care of that I think the last thing he will do is reverse course," she said.
Phoenix Mayor Greg Stanton issued a statement that said in part:
The Phoenix Police Department will never turn into a mass deportation force, even if the new government in Washington, D.C., threatens to revoke federal dollars. This is something worth fighting for, and we will not be bullied into taking backward steps on civil rights.
During his campaign, Trump's immigration plans were endorsed by two Valley residents whose children were killed by undocumented immigrants with criminal records.
Maryann Mendoza's son, Mesa Police Sgt. Brandon Mendoza, was killed by a wrong-way driver. Steve Ronnebeck's son Grant was gunned down while working at a convenience store.
A Phoenix Police Department spokesman declined to speak on camera about Trump's plans. The department referred 12 News to its orders for officers on immigration enforcement:
The Department shall conduct all immigration enforcement activities in a manner consistent with federal and state laws regulating immigration and protecting the civil rights, privileges, and immunities of all persons.
