Members of the local immigrant community are accusing Brown of blocking the city's efforts to opt out of a controversial federal fingerprinting program. The program, known as Secure Communities, requires cities to send the fingerprints of everyone arrested by federal immigration authorities.
San Francisco has tried to remove itself from the voluntary program before but was told by the attorney general's office that it couldn't and that it was important to work with the federal government on the issue.
Several people have been arrested.
