After an undercover NYPD officer infiltrated their group at Brooklyn College, Muslim students there are learning to protect themselves. And dozens of similar "know your rights" seminars are being held across New York City following an AP report that revealed the police department's widespread surveillance of the Muslim population.

"We're doing what we believe we have to do to protect the city," NYPD Commissioner Ray Kelly said in August. "We see ourselves as very conscious and aware of civil liberties."
