San Francisco officials are warning anti-Wall Street protesters camped out in a city plaza that they face arrest if they continue to stay there around the clock. In a notice distributed on Tuesday, Police Chief Greg Suhr said the protesters in Justin Herman Plaza could be arrested on a variety of sanitation or illegal camping violations although police are not saying when that could occur.
