I thought the French media had the better perspective, they distinguish between the bulk of the demonstrators and the 'casseurs', the people who are there to break things. The Germans have the 'chaoten', the chaos producers.
These individuals rely on the cover of the mass demonstration to perform violent acts, in the expectation of creating worse. It seems a form of political terrorism which is very effective. The sponsorship would be very interesting imho.
