Is this the end of Occupy Wall Street? The NYPD cleared the protesters’ headquarters in Zuccotti Park early Tuesday. At 1 a.m., cops began handing out notices from the park’s owners that it had to be evacuated so it could be cleaned; the protesters could return later, police said, but without sleeping bags, tarps, or tents. Most protesters left, but about 100 built a barricade at the park’s center and some chained themselves together. By 4:30 the park had been cleared and 70 people had been arrested. Protesters had been planning to “Shut Down Wall Street” on Thursday to celebrate their two-month anniversary.
