It wasn't the Anarchists who ran amok at the WTO meetings and elsewhere. This was almost entirely the work of undercover law enforcement who were creating a cause for breaking up the rallies. This is well documented by independent media outlets like DemocracyNow and others.

Anarchists are alive and well. Understand Anarchists aren't about lawlessness, but they have realized the truth of governments, which is that governments create laws that infringe upon civil rights and create classes set against one another in order to insulate the elite and to maintain the ruling class' position of power.
