The fourth week of Occupy Wall Street begins today. It has grown so big that it can no longer contain the ten thousand or more people that come to the park regularly each evening. The “people’s mic” or “human mic” has become much more difficult as lines of speeches have to be echoed three and four times so all in the park can hear what people have said. The occupation also needs to keep raising the stakes and escalating the situation to keep up the energy and momentum. And so, today at 3 pm ET part of the encampment will relocate to Washington Square Park.
