Police think that it's a matter of "infighting." I'm thinking more along the lines of ex-cons who are freeloading.

Whatever the reason, there's an entire section of Zucotti park that people won't go.

USA Today:

Police officers also have been warned of "dangerous instruments" being concealed in cardboard tubing, the News says it has been told by unidentified police sources.

"There is a lot of infighting in the park," a police source told the news organization. "There is one part of the park where they won't even go at night."

Meantime, Ed Mullins, president of the Sergeants Benevolent Association, is warning protesters at Zuccotti Park in Manhattan that he will pursue civil suits against anyone who assaults a union member.

"New York's police officers are working around the clock as the already overburdened economy in New York is being drained by 'occupiers' who intentionally and maliciously instigate needless and violent confrontations with the police," the News reports Mullins said in a statement.

But protesters tell the News they have been the victims of police brutality, not the other way around.

By the way, USA Today has been flogging the OWS story nationwide. Here's an entire page devoted to updates around the country from various protest sites. And how's this for advocacy journalism:

Are you participating in the protests? Even if you aren't, you don't need to stay silent. Share your opinions through USA TODAY Opinion. Send your story in video, photos and text to letters@usatoday.com.

That doesn't sound very welcoming of alternative views on OWS, does it?
