My experience with the feds isn't the brightest of paintings but don't take it from me... This article sheds a lot on the current landscape of the relationship of the Muslim American community and American intelligence agencies.
In 2007, Niazi reported suspicious behavior by a new Muslim convert in his mosque, who he said was talking about jihad and suggested planning a terrorist attack in conversations with others at the Islamic Center of Irvine. He and a mosque official filed a report with the Los Angeles field office of the FBI. The FBI then told mosque officials that they were investigating the matter, and the mosque successfully got a three-year restraining order against the individual.
Niazi reported that FBI officials later contacted him to ask him to be a paid informant. When he refused, he said they threatened to make his life "a living hell." Niazi was arrested last week on charges related to lying on his immigration documents and was released yesterday on $500,000 bail.
