On Day 13 of the Wall Street demonstrations, protesters marching against what they call corporate greed and America’s “corrupt” democratic processes said they would go to police headquarters Friday, in what many say will be a test of whether tensions will escalate, MSNBC reports.

Police have said that they responded “appropriately,” and that pepper spray was a better alternative than night sticks.

The few hundred remaining protesters also say they are in for the long haul, and are forming a “winterization committee” to prepare for the cold season.
