Pete Seeger marches with Occupy Wall Street. Did the police join in?

One couldn't help but be moved by the sight of 92-year-old folk-music legend Pete Seeger (making good time even as he used two canes for ambulation), marching through New York City's Upper West Side last night with throngs of singing and chanting Occupy Wall Street protesters. His grandson, Tao Rodriguez Seeger, accompanied the crowd on guitar and someone else was playing a flute. (The video feed that carried the event streams live around the clock from Zuccotti Park. I've added it to this site.) You didn't have to be an activist or a dyed-in-the-wool folkie for this to qualify as a three-hankie moment.

Michael Moore, who's making a documentary about the Occupy Wall Street movement, was there too. This morning I awoke to his tweet. "OMG! A few cops joined in the march tonite! A 1st! 2 of them were even singing along w/ the crowd! In Egypt, when cops joined in...game over." I'm new to Twitter, so my search skills are not yet honed, but I could not find any tweets to confirm the one from Moore. Predictably, there's been a lot of retweeting of Moore's initial report.

I'm neither a fan nor a detractor of Michael Moore. He's obviously done some good in the world with his unorthodox and incendiary documentary film-making. He would also seem to massage facts to suit his purpose on occasion. Because of this, I watch his movies with a certain skepticism. Moore has publicly called for the police to join Occupy Wall Street "the same way the Egyptian army joined the people in Freedom Square there in Cairo."

 
Did the cops join in last night? If they did, it's significant and should be reported on. Someone besides Michael Moore must have seen it. You won't find it in the Wall Street Journal, which said the protesters "marched peacefully over more than 30 blocks from Symphony Space, where the Seegers and other musicians performed, to Columbus Circle. Police watched from the sidelines."
 
We'll see if the story of police officers falling in with the protesters turns up in a credible media source. In times like these, it's hard to know who to believe.
