The problem with small groups dedicated to creating trouble of any kind, is that the actions of such minority groups (who may - or may not - also be members of the larger group), will almost certainly be used as an excuse for the govt. to implement more repressive strategies in regards future demonstrations. That is not what's needed right now. The waves of public dissent need to build, not be immediately diverted by a small group of dedicated political activists getting themselves on telly for their 15 minutes of fame. The "anarchists" are playing straight into the hands of the system they supposedly wish to dismantle.
