Looks like the actual trouble makers in NY may be the RNC delegates (from wapo):

Moore first attracted attention about 8:45 p.m. as he walked slowly over the temporary bridge that connects the media spillover building to Madison Square Garden. Stopped by a handful of reporters, Moore began to hold court. Video camera lights quickly popped on, and the knot around Moore grew.

It quickly became a crowd-control issue, and officials began trying to corral the unruly scribes. "You were told to stop," shouted one police officer as reporters tried to break through his hallway cordon. "If you don't, I can arrest you."

This set off grumbling in the mob, with several reporters asserting their sacred First Amendment right to chase a celebrity through the corridors of a sports arena.

"This is my big rugby scrum," Moore said, explaining the scene around him to a security guard. "It's a dangerous situation here," yelled a plainclothes NYPD officer. "Please make a lane. Please make a lane."

A delegate from Missouri called Moore a "disgrace," a few seconds after asking for his autograph.

"I could kick his [rear]," said Steven R. Schirripa, an actor on "The Sopranos" who is here as a "correspondent" for NBC's "Tonight" show. "We need to get this Moore guy on 'The Sopranos' in case we need to whack someone."

"I think that guy's the most disgusting human being I've ever seen," said Jimmy Gilbert, a 66-year-old alternate from Lenoir, N.C.
