I don't know which guy you mean, but if you're referring to Yeshilita(sp?), this is not the first time he has, literally, incited a riot. Several blocks of old St. Pete were burned and looted to the ground a few years ago with this racist leading the charge, and nothing was done about him then. He even called openly for the murder of the mayor and police chief.
The authorities here won't/can't touch him, but one of these days he's gonna be in the wrong place at the wrong time...
