At Christine Quinn Campaign Fundraiser, do NYPD work as Private Security ?

Is Speaker Quinn using city resources, and police,
for campaign activities ?

At a political fundraiser on the evening of Feb. 2, 2011, City Council Speaker Christine Quinn deployed a large team of police officers. Three peaceful protesters, myself included, gathered to hold up a banner, asking for a new hospital for the Lower West Side of Manhattan, to replace St. Vincent's. Police told us to move, and one officer pushed me to get me to move, even though we were on a public sidewalk and not blocking traffic. Plus, there were no barricades, to indicate that there was a restricted zone. Is Speaker Quinn using city resources, and police, for campaign activities ? Who is instructing NYPD to intimidate protesters ?
