October 5, 2011 marked the 18th day of Occupy Wall Street, a protest that has filled a small park in downtown Manhattan for weeks and sparked copycat protests across the country and abroad. Hundreds have been arrested over the past few weeks — at least 20 were arrested last night — and the world has its eyes on Liberty Square, where the protesters have made their encampment.

Below, see photos of a day with the movement.
