As the Occupy Wall Street protests continue, Yolanne Almanzar, reporter for The New York World, discusses a new project about privately owned public spaces like Zucotti Park, and a crowdsourcing project where you help find out how public these public spaces are. She's joined by Jerold Kayden, professor of urban planning and design at Harvard and author of Privately Owned Public Space: The New York City Experience, who explains why privately owned public spaces exist and how they differ from city- and state-owned public parks.
