Late at night on Wednesday, protesters at Zuccotti Park in New York were outnumbered by police. But every now and then a new protester would come into the park and just stare at the space like they were looking at it for the first time.
Jo Robbin, 29, was one of them. One of the first things she did as soon as she made it past the security check point was pull up her sleeves to show the red markings the plastic ties had left her.
