What could entirely change the complexion of this little affair would be for Michael Bloomberg to feel personally threatened by the demonstrators. That is, feeling that they want to not just humiliate him, but assassinate him.
Imagine if the NYPD were given license to clear the street? Or to arrest each and every protestor? Think they could pull it off?
I like the idea of herding them as a mass down to the East River, where large boats would be waiting.
They already have that. NYC is NOT a good place to hold a protest.
