Secure Communities (S-COMM):
ICE (Homeland Security's Immigration & Custom Enforcement division) announced in mid-August that it would not allow states and municipalities to opt out of S-COMM: the program where local law enforcement agencies send arrest information to ICE for deportation consideration:

"For decades, local jurisdictions have shared the fingerprints of individuals who are booked into jails with the FBI to see if they have a criminal record. Under Secure Communities, the FBI automatically sends the fingerprints to ICE to check against its immigration databases."

The SF Bay Area rallied against S-COMM on August 12th by a march from Sen. Dianne Feinstein's office at Market & Post to ICE headquarters at Sansome & Washington where Laura Rivas from the National Network for Immigrant & Refugee Rghts (NNIRR) was among those who spoke.
