Protests against the acquittal of George Zimmerman in the shooting death of unarmed African-American teenager Trayvon Martin continued across the country Monday. In Los Angeles, at least 13 people were arrested overnight as police accused some protesters of vandalizing cars, breaking windows and setting fires. The Los Angeles Police Department first declared a tactical alert and then an unlawful assembly, allowing them to arrest protesters who did not clear the streets. Meanwhile in Oakland, hundreds of protesters blocked traffic on Interstate 880 during rush hour Monday evening. At least six people were arrested. Attorney General Eric Holder addressed the Zimmerman verdict Monday during remarks before the African-American sorority Delta Sigma Theta.

Eric Holder: “We are also mindful of the pain felt by our nation surrounding the tragic, unnecessary shooting death of Trayvon Martin in Sanford, Florida, last year. And we are cognizant of the fact that the state trial reached its conclusion over the weekend. As parents, as engaged citizens, and as leaders who stand vigilant against violence in communities across the country, the Deltas are deeply, and rightly, concerned about this case. The Justice Department shares your concern. I share your concern. And as we first acknowledged last spring, we have opened an investigation into this matter.”
