Protesters circle NY's Zuccotti Park

New York Mayor Bloomberg says the park will remain closed until the issue of the court order is settled

Protesters are circling Zuccotti Park, chanting: "Whose park? Our park!" while the space inside has been thoroughly scrubbed and cleaned. Earlier this morning the smell of disinfectant was in the air.

The protesters firmly believe that a court order means that they should be allowed back into the square. That is the interpretation of the protesters' lawyers, too.

But the police - in full riot gear - do not agree and are ringing the metal barriers that are blocking off the park.

The mood seems to change by the minute. For a few moments it is angry and confrontational. Then the demonstration seems almost dutiful, by rote, and then there is a sudden mood of celebration as a trumpet plays a Mariachi tune.

One man tells me that they are going to force their way back in. He tells me: "There is a tsunami on the way."

Another man warns the police: "We're on for a rumble."

But they are very much in the minority and there are a large number of people carrying banners urging non-violence.

What really interested me was talking to some construction workers who are working on the World Trade Center site.

They all tell me the same thing: first, they are glad the protesters have gone and the space where they used to eat their sandwiches or smoke a cigarette is now clean again. They say the protesters were "riff-raff".

But to a man and woman, they seem almost amazed when I ask about their cause.

"Of course they're right. The banks got the bail out, didn't they? We didn't."
