NY1: UFT: It Appears that NYPD is Spying on Teachers

In an exclusive report by NY1, "NY1 Exclusive: Teachers Union Says NYPD Keeping Close Watch Following Support Of Protests," the United Federation of Teachers, New York City's teachers' union asserts that the New York Police Department might be spying on teachers, particularly in light of the UFT's support of the Occupy Wall Street protests at Zuccotti Park.
Here are opening excerpts from Lindsey Christ's October 21, 2011 report:

The United Federation of Teachers has vocally supported the “Occupy Wall Street” movement, and union representatives now say they believe the New York City Police Department may be spying on them as a result. NY1’s Lindsey Christ filed the following report.

Police cars are not usually parked outside the headquarters of the United Federation of Teachers, but union representatives say they've been there for the past few weeks.

Union leaders say they think they've been put under surveillance by the New York City Police Department ever since they began supporting “Occupy Wall Street.”
