The number of non-participants taking advantage of the resources that the activists have provided — free food, clothing, tarps and sleeping bags, hand-rolled smokes and even books, not to mention a sense of protection from the police, who have increasingly left the park to protect itself - has exploded over the past week, and is threatening to define the occupation itself and overshadow its political and social ambitions. Despite those resources, “spanging” (spare-changing, or panhandling) at Zuccotti has become commonplace, as have fights, near-fights and open-air drug sales.
