This video is from Union Square Park this week as the NYPD forced Occupy Wall Street protesters out of the park area after declaring it closed for the night for "cleaning."

Were these cops ordered to attempt to incite a riot with their repeating "They're throwing glass bottles! They want to hurt us, guys!" ? Was it a training exercise of some sort? All of these officers appear quite young, and perhaps are new to the force, so an "on-the-job-training" exercise seems possible.

The occupier speaking during this altercation claims that there was a bottle thrown, but that it was tossed by an undercover cop planted in the crowd.
