Standing outside of his store, Abdul Kareem Abdullah, is interviewed by the Associated Press regarding New York Police Department surveillance of the Muslim community in Newark, N.J., Wednesday, Feb. 15, 2012. Americans in New Jersey’s largest city were subjected to surveillance as part of the New York Police Department’s effort to build databases of where Muslims work, shop and pray. The operation in Newark was so secretive, even the city’s mayor says he was kept in the dark. For months in mid-2007, plainclothes NYPD officers snapped pictures of mosques and eavesdropped in Muslim neighborhoods. The result was a 60-page report, obtained by The Associated Press. It cited no evidence of crimes. It was just a guide to Newark’s Muslims. (AP Photo/Charles Dharapak)
