October 15th marked the Global Day of Action and saw marches in major cities across the globe. In the New York, the protesters at Occupy Wall Street, who have been encamped at Zuccotti Park since September 17, joined in. According to organizers at least 6000 people showed up in Times Square.
One of the many issues people protested was the War on Terror™. I rather liked this sign against the backdrop of the NYPD station in Times Square. :)
