@Zoohouse a call to action for people to riot would be, but thats not what he did. Inciting a riot in and of itself (without an explicit call to action) is not illegal. He never asked anyone to riot or to be violent and moments after they did he went on tv and asked them to go home.
So no real evidence there of anything illegal, just a man being an idiot and some people who believed him and took it too far
