Riot or protest?

Is it mindless rioting or criminal looting or the protest of a disenfranchised youth? There is no reason why it can't be all three. I hesitate to pontificate on the recent goings on in London and elsewhere because so many words have been expended on the subject so far anyway. It does seem though that people have been divided widely on the subject. I doubt that I will add anything to the debate by adding my two-pennyworth so I will keep my counsel and move on to other things.
