Yesterday morning, when I learned that Zuccotti Park had been cleared overnight by New York City Mayor Michael Bloomberg — who justified his action in a statement that cited health and safety concerns — the first thing I did was call my lawyer. I wanted to go and show my support for the protesters’ First Amendment right “to assemble and petition government for redress of grievances” — a right that a 1925 Supreme Court decision confirmed superseded municipalities’ laws that sought to restrict its exercise. But my partner and I had already been arrested on Oct. 19 for standing peacefully on Hudson Street after informing protesters outside an event I was attending of their right to assemble. The wonderful National Lawyers Guild advised us that we would probably be O.K. — the New York police department would have to alert us before a second arrest.
