Protesters and police in Anaheim continued to clash late Tuesday night after officers declared an unlawful assembly and fired less-than-lethal projectiles at angry crowds near City Hall.At Santa Ana Street and Anaheim Boulevard, people grabbed rocks from a construction site and hurled them at officers. Others lighted a fire in the weeds and in trash bins in the area as they were chased by police. Other officers farther south on Santa Ana street fired bean bags at protesters on the fourth day of protests following the deadly police shooting of two men over the weekend.
