CNN just updated the story, and it looks like there were 5 black guys calling themselves Hebrew Israelites who were taunting and spewing hate, and then the kids noticed them, and this guy went in between trying to keep things calm, and the kids started chantng with him, and then this kid ....etc. so .....this turn of events is not explained, but the kid was abnoxious and threatening to him.
Good for CNN to look into this, something FAUX would never do.
