please take a look to my 2 other photographic essays concerning #OccupyWallStreet here and here
The movement #OccupyWallStreet also known as #TakeWallStreet is clearly growing since their first protest last Saturday (07/19/2011).
Today, they were in Union Square, not "only" marching around the Financial District.
Concerning the photos you will see below, I can testify about the blond woman in the first photos that she only shouted "Take the streets" and nothing else and that was the only reason the New York City Police Department (NYPD) arrested her so brutally
I don't know why they arrested the others on the photos.
The NYPD communicated to the press that they arrested 85 people .. most of them because were blocking the traffic. More official information here
Tuesday 20th of September 07h20 AM New York Time, I was taking photos to the pacific supporters of #OccupyWallStreet ( https://occupywallst.org/) when, Justin, who was speaking with a megaphone (considering the big noise around the LIBERTY Square located on the Financial District of Manhattan , New York) has been brutally and for obscure reasons by the NYPD.
Take a look to my coverage with a little bit of Art and humour including a sad and frequent street photo I take just 3 minutes after the arrest very near of what it is called LIBERTY Square and where the protesters are based since Saturday 19th of September.
