Liberty Plaza is now surrounded by police barricades. A mobile NYPD surveillance tower gives the park a prison camp look. I saw familiar faces, like retired Philadelphia police captain and the man from Queens who wants everyone to move their money out of the big banks. A discussion group was in progress. I was told that Jackson Browne showed up this week and played some songs. The park isn't necessary anymore, I believe, and the movement moves onward. It is still worth visiting.
