This are the shocking scenes that have led some people to accuse the Occupy Wall Street protesters living rough in New York's financial district of creating unsanitary and filthy conditions. Exclusive pictures obtained by Mail Online show one demonstrator relieving himself on a police car. Elsewhere we found piles of stinking refuse clogging Zucotti Park, despite the best efforts of many of the protestors to keep the area clean. The shocking images demonstrate the extent to which conditions have deteriorated as demonstrations in downtown Manhattan enter their fourth week.
