The good mayer needs to put down his chalupa and get the LE's out there to bust some heads.
The linked TV news story reported only 4 were arrested. With that level of mob violence and assault, the mayor is sending a message loud and clear in support of the violent, Mexican flag waving thugs.
They're waving Mexican flags and they burned an American flag yet they fled Mexico to come to America. They held signs reading "Make California Mexico again" yet they fled Mexico and came to California.
That can only make sense to a leftist.
