Continuing street protest over police shootings in Anaheim turned ugly last night with rocks thrown at officers and fires lit in weedy lots and trash cans. Genevieve Huizar, mother of Manuel Diaz, one of the men killed, pleaded for peace… Huizar says her son was shot in the back and then executed when he fell to his knees. The Anaheim police union says an officer fired in self-defense because Diaz was holding a “concealed object in his front waistband with both hands.”
