Yes they really are worried about them aren't they?
I've been musing about the fact that even when a protest is peaceful the authorities and the media are looking for a way to undermine the protest using suggestions like this and accusations that the protesters are 'professional' protesters.
Have we really lost sight of the fact that it is a democratic right to protest provided no violence is used and that the law is not broken.
I think the beaten and shot protesters in Syria would love to be able to just occupy a square or two without having to risk being shot.
