"(CBS/AP) Police with water cannon fired tear gas and rubber bullets Saturday to separate violent demonstrators from a protest opposing a meeting of top world trade officials, but the hooded 'black bloc' activists were able to cause damage before 14 were arrested, spokesmen said.
"The protesters set fire to at least four cars, broke shop windows and committed other acts of violence Saturday, police spokesman Patrick Puhl said."
The Black Bloc uses such underhanded, vicious tactics that it's not much of a stretch to assume that its members are Satanists. The actual purpose of its "hooliganism" is to make it more difficult for genuine protesters to conduct their protests and get media attention. Another perspective on its activity is that it symbolizes the destructive "free trade" agenda behind the WTO, against which the Black Bloc was supposedly protesting.
