In light of reports that police have been cracking down on the Occupy Wall Street protesters, many have wondered what the protesters did to provoke the NYPD. But Jeanne Mansfield’s first-hand account of the weekend’s police brutality shows that the protesters — who have been trying to stand against Wall Street’s greed and corruption — were only marching when police officers corralled them in and began to mace them.

As we circle Union Square, about twenty NYPD officers haul out orange plastic nets (the kind used to fence off construction sites) and close off the road, diverting the crowd. But the detour, too, is closed, leaving us only one option: straight down Broadway. The lighthearted carnival air begins to get very heavy as it becomes clear that we are being corralled. The main group, about 150 protesters, keeps on down the street, but the police are running behind with the orange nets, siphoning off groups of fifteen to twenty people at a time, classic crowd control.

A new group of police officers arrives in white shirts, as opposed to dark blue. These guys are completely undiscerning in their aggression. If someone gets in their way, they shove them headfirst into the nearest parked car, at which point the officers are immediately surrounded by camera phones and shouts of “Shame! Shame!”

Up until this point, Frank and I have managed to stay ahead of the nets, but as we hit what I think is 12th Street, they’ve caught up. The blue-shirts aren’t being too forceful, so we manage to run free, but stay behind to see what happens. Then things go nuts.

The white-shirted cops are shouting at us to get off the street as they corral us onto the sidewalk. One African American man gets on the curb but refuses to be pushed up against the wall of the building; they throw him into the street, and five cops tackle him. As he’s being cuffed, a white kid with a video camera asks him “What’s your name?! What’s your name?!” One of the blue-shirted cops thinks he’s too close and gives him a little shove. A white-shirt sees this, grabs the kid and without hesitation billy-clubs him in the stomach.

At this point, the crowd of twenty or so caught in the orange fence is shouting “Shame! Shame! Who are you protecting?! YOU are the 99 percent! You’re fighting your own people!” A white-shirt, now known to be NYPD Deputy Inspector Anthony Bologna, comes from the left, walks straight up to the three young girls at the front of the crowd, and pepper-sprays them in the face for a few seconds, continuing as they scream “No! Why are you doing that?!” The rest of us in the crowd turn away from the spray, but it’s unavoidable. My left eye burns and goes blind and tears start streaming down my face. Frank grabs my arm and shoves us through the small gap between the orange fence and the brick wall while everyone stares in shock and horror at the two girls on the ground and two more doubled over screaming as their eyes ooze. In the street I shout for water to rinse my eyes or give to the girls on the ground, but no one responds. One of the blue-shirts, tall and bald, stares in disbelief and says, “I can’t believe he just fuckin’ maced her.” And it becomes clear that the white-shirts are a different species. We need to get out of there.

There was an anger in those white-shirt’s eyes that said, “You don’t matter.” And whether they were just scared or irrational or looking for a target for their rage, there was no excuse for their abuse of authority. I had always thought that people who complained about police brutality must have done something to provoke it, that surely cops wouldn’t hurt people without a really good reason. But they do. We were on the curb, we were contained, we were unarmed. Pepper spray hurts like hell, and the experience only makes me wish I’d done something more to deserve it.
