F.B.I. counterterrorism agents monitored Occupy Wall Street movement

From The New York Times:

WASHINGTON — The Federal Bureau of Investigation used counterterrorism agents to investigate the Occupy Wall Street movement, including its communications and planning, according to newly disclosed agency records.
The F.B.I. records show that as early as September 2011, an agent from a counterterrorism task force in New York notified officials of two landmarks in Lower Manhattan — Federal Hall and the Museum of American Finance — “that their building was identified as a point of interest for the Occupy Wall Street.”
Occupy Wall Street has lost much of its visibility since then, but questions remain about how local and federal law-enforcement officials monitored and treated the protesters.
