Beyonce attended the Justice For Trayvon rally that was held in New York City with Jay-Z, Tina Knowles, and her cousin Angie. Rallies seeking justice for slain teen Trayvon Martin have been planned for 100 cities across the U.S. today. George Zimmerman was acquitted on second-degree murder and manslaughter charges in the shooting death of the unarmed teenager last week, and the rallies were organized by Rev. Al Sharpton’s National Action Network to push for civil rights charges to be filed against Zimmerman.
