MANHATTAN - Thousands of people, some of them from Long Island, marched alongside union members tonight as part of the ongoing Occupy Wall Street protest. "We're just so excited to see a natural, organic movement of regular people coming out to say, 'This is crazy,'" says Lisa Tyson, director of Long Island Progressive Coalition.Tyson's group spent the day today making signs and posters in its Massapequa office to bring into Manhattan. She says the group is rallying against corporate greed and social inequality, and its goal is to make the wealthy pay more. "This is about corporations trying to steal every dollar from this country," Tyson says.The Occupy Wall Street protest got under way more than two weeks ago. Since then, demonstrations have been taking place from Boston to Seattle, and over the weekend, the NYPD arrested about 700 people for protesting on the Brooklyn Bridge.
