The police state is here! Law enforcement now the "hired guns" of the plutocrats

You can see here police in Oakland using tear gas, shock grenades and other heavy handed tactics to break up the Occupy Oakland demonstration. Once again, peaceful demonstrators exercising their Constitutional right are beat down by the police state. Who are the police protecting? Property's is not being damaged or destroyed, no one is being threatened, so we can only assume conclude that law enforcement in the US has becomme the "hired gun" of the plutocracy. Democracy itself is threatened.
