Both of Tucson's largest police agencies say "this is the law and we will enforce it."
For Tucson's Roberto Villasenor, who has been an outspoken critic of the "paper's please" provision of SB 1070, because he feels it will distract from a law enforcement's priorities, "keeping the community safe."
He says his officers have been training on how to enforce the provision for the past two years and he has sat in on most, if not all the sessions.
He feels the provision will put up a wall between law enforcement and the community he serves.
"I'm sure it will change some peoples opinion of law enforcement, contacting law enforcement and that's something I am not pleased about," he says.
That's a concern he shares with Pima County Sheriff Clarence Dupnik, that people won't call when they're in trouble or need help because of their fear of law enforcement.
It creates an atmosphere of fear for both legal and illegal residents.
"I can't guarantee you won't be profiled tomorrow, nobody can," says Dupnik. "That's an unreasonable expectation."
Dupnik says his agency has been practicing the papers please philosophy since he came on the force more than 52 years ago.
"We don't ask for papers but if there's evidence the person is in the country illegally, we will pursue it," he says.
But for him, "it's making a mountain out of a mole hill."
While he says he's never been accused of racial profiling, "our cops are human beings."
Villasenor says he's more concerned with the political implications of the new provision and the people with an agenda.
"I don't believe this will increase racial profiling," he says. "Because people are so sensitized to this right now it will increase the accusations of racial profiling."
A federal judge has ruled that Arizona authorities can enforce the most contentious section of the state's immigration law, which critics have dubbed the "show me your papers" provision.
The ruling Wednesday by U.S. District Judge Susan Bolton clears the way for police to carry out the 2010 law's requirement that officers, while enforcing other laws, question the immigration status of those they suspect are in the country illegally.
The requirement has been at the center of a two-year legal battle that culminated in a U.S. Supreme Court decision in June upholding the requirement.
Opponents then asked Bolton to block the requirement and argued it would lead to racial profiling of Latinos.
Less controversial sections of the law have been in effect since late July 2010.
The governor's office says the law is expected to go into effect shortly.
Tucson Police Department says they are reviewing the decision and will get more guidance on specific enforcement. TPD says they will "abide by the ruling in its entirety."
Tucson News Now has scheduled to sit down with Tucson police tomorrow.
Gov. Brewer released the following statement:
"Today, Arizona is one big step closer to implementing the core provision of SB 1070. I applaud the federal court for siding with the U.S. Supreme Court in refusing to block the most critical section of this law, which will empower state and local law enforcement, as part of a legal stop or detention, to inquire about an individual's immigration status when the officer has reasonable suspicion. With this provision, Arizona makes a clear statement that it will not tolerate sanctuary city policies, and will now have thousands of additional officers to collaborate with the federal government as state and local law enforcement do what they always have: enforce the law.
"After more than two years of legal challenges, it is time that Section 2(B) of SB 1070 take effect. Given today's ruling, along with the federal court's suggestion that it intends in the very near future to formally lift the existing injunction, it is clear the day of implementation is fast approaching.
"As I have said consistently, it is not enough that this law be enforced. It must be enforced efficiently, effectively and in harmony with the Constitution and civil rights. I have no doubt Arizona's law enforcement officers are up for the task ahead."
