Excerpt:
New Jersey law enforcement leaders have denied knowing about widespread surveillance of Muslims by New York City detectives, but state police agencies were involved in at least one joint effort: the monitoring of a Paterson mosque.
State authorities worked with the New York City Police Department to monitor the Islamic Center of Passaic County, led by Imam Mohammad Qatanani, police documents show. The surveillance included the use of an informant at the mosque and intelligence gathering during a three-day rally for the imam in his fight against deportation.
Because of his strong relationship with law enforcement leaders, Qatanani said, he was taken aback by news of New Jersey's involvement.
