City Attorney Herrera has obtained civil injunctions against five violent street gangs that have long plagued San Francisco neighborhoods with their criminal and nuisance conduct. Named in the gang injunctions so far issued by the San Francisco Superior Court are the following:
- The Bayview/Hunters Point-based Oakdale Mob
- The Mission-based Norteño gang
- The Western Addition-based Chopper City gang
- The Western Addition-based Eddy Rock gang
- The Western Addition-based Knock Out Posse gang
Herrera is currently pursuing a new injunction against two more gangs:
- The Visitacion Valley-based Down Below Gangsters
- The Visitacion Valley-based Towerside Gang
The Effectiveness of Civil Gang Injunctions in S.F.
Tracking arrest data since the imposition of each gang injunction, the San Francisco City Attorney's Office has observed a general "cooling off" effect among gang members named in the various injunctions, with markedly fewer arrests citywide following the imposition of injunctions. Since San Francisco's gang injunction program was launched at the end of 2006, 46 percent of identified gang members (43 of 93) have gone without even a single arrest in San Francisco for crimes other than minor violations of the injunction itself. The data also show progressive improvements over time, with only 14 percent of identified gang members (13 of 93) arrested for non-injunction crimes so far in 2010 -- down from 41 percent in 2007.

To date, no injunction has resulted in an observable migration of gang-related crime or nuisances to adjacent areas or to different neighborhoods, as evidenced by citywide arrest data and observations by experts from the San Francisco Police Department's Gang Task Force.
In addition to the statistics on the effectiveness of San Francisco's gang injunction program, the following are two independent studies of civil gang injunctions in other California jurisdictions that indicate their effectiveness in helping to abate gang-related violence and nuisance activity.
How to 'Opt-Out' of a Gang Injunction
An agreement among the City Attorney's Office, the American Civil Liberties Union of Northern California and the Lawyers' Committee for Civil Rights of the San Francisco Bay Area has established an administrative process by which individuals named in civil gang injunctions may petition to "opt out" from the court ordered provisions.
City Attorney Herrera said the opt-out process "both maximizes civil liberties protections for alleged gang members, and ensures the effectiveness of civil gang injunctions to protect San Francisco neighborhoods from violence and nuisance conduct."
Civil Gang Injunction in Visitacion Valley
On Aug. 5, 2010, the San Francisco City Attorney's Office filed suit against two warring criminal street gangs that have terrorized San Francisco's Visitacion Valley for more than three years. The civil complaint filed in Superior Court names the "Down Below Gangsters" and "Towerside" gang as defendants in an action that seeks to prohibit an array of gang-related criminal and nuisance conduct by 41 adult gang members within a proposed "safety zone" covering less than two-tenths of a square mile.
The proposed safety zone is an approximately .18 square mile "L" shaped area bordered by Schwerin Avenue, Visitacion Avenue and Hahn Street, and the Sunnydale Public Housing Development's northern, western and southern borders, the latter of which then proceeds along Velasco Avenue. The safety zone encompasses both known gang turfs together with an adjoining buffer zone between and near the two turf areas.
