Still, San Francisco is a city that strongly opposes federal immigration sweeps,
and immigration agents are among those joining the FBI, the Drug Enforcement Administration, U.S. Marshals Service and others in the effort. San Francisco was a sanctuary city before the rest of California largely pledged not to work with federal authorities on deporting people in the country illegally.
San Francisco Supervisor Matt Haney, whose district includes the Tenderloin, said residents are fed up with dealers using the neighborhood as a dumping ground for drugs. He supports assistance focused on top-tier investigations but says the city needs to remain vigilant on immigration.
"I hope that this isn't a way to get around San Francisco sanctuary laws," he said. "There can be an important role for the U.S. attorney in going after higher level individuals, and I hope that is where they would put their focus."
Bill Ong Hing, a former member of the city's police commission and director of The Immigration and Deportation Defense Clinic at the University of San Francisco School of Law, said the initiative should not affect San Francisco's sanctuary policies so long as federal officials stay clear of city help.
"The police department will not partner with them on that activity," he said. "At least, they're not supposed to."
