Yep. Lots of idiots on both sides. Two groups that hate each other facing off in large numbers. It was bound to get ugly.
You need to understand, some of these people were followed into parking lots as they attempted to leave the area. Video exists which I’ve personally reviewed, showing several being literally pinned against their vehicles by large violent antifa crowds, as they were attempting to leave the area. One was lucky to escape without being beaten to death.
