Yesterday marked the biggest day yet for the Occupy Wall Street protest in NYC. 30,000 protesters and union members linked arms and marched down Broadway towards Wall Street.

As the procession neared Wall Street, around 200 people broke off from the crowd and approached the street where it intersects Broadway. 

That's when the NYPD literally beat back the protesters - officers used a mix of batons and clouds of pepper spray to subdue their unarmed quarry.
