Police arrest dozens of protesters - attempting to march on the New York Stock Exchange Thursday morning.Dragging some demonstrators and pining others to the ground, New York City police officers scuffled with the Occupy Wall Street protesters - who had gathered just blocks away from the financial center. 　　Billed as a "Day of Action" - the demonstrators had hoped to interrupt business - by marching from a nearby park and preventing financial workers from getting to their desks. Now a two-month old movement - the Occupy Wall Street protesters oppose what they say is an unjust economic system - that favors the wealthiest one percent - at the expense of the other 99.
