Documents provide rare insight into FBI's terrorism stings "I had a feeling that I had just played out a part in some Hollywood movie where I had just been introduced to the leader of a "terrorist" sleeper cell," Akili wrote. When he googled a phone number provided by the second man, it turned out to be to Shahed Hussain, one of the FBI's most prolific and controversial informants for terrorism cases. Soon the sting was off; Akili was subsequently arrested on gun - not terrorism - charges, which he has denied. It was a rare miss for Hussain, 55, who has played a wealthy, dapper member of a Pakistani terrorist group in several FBI operations over nearly a decade. This role has inflamed Muslim and civil rights activists, who describe Hussain as an "agent provocateur," and prompted harsh comments from the presiding judge in a 2010 case, who questioned his honesty and the aggressiveness of the FBI's tactics. "I believe beyond a shadow of a doubt that there would have been no crime here except the government instigated it, planned it and brought it to fruition," said U.S. District Judge Colleen McMahon at the sentencing of four men from Newburgh, N.Y., convicted on terrorism charges. She added, "That does not mean there was no crime." Hussain declined to speak about his work for the FBI, saying in a brief phone interview, "I can't say anything for security reasons." The FBI declined to discuss Hussain or McMahon's comments. But the blown Pittsburgh sting and the voluminous court records from the 2010 case have provided rare insight into a tactic used increasingly by the FBI since the Sept. 11, 2001, attacks in which suspects are monitored almost from the beginning of plots and provided with means to help them carry them out. The targets in such stings have included Washington's Metro subway system, the Pentagon and the U.S. Capitol. There have been 138 terrorism or national security cases involving informants since 2001, and 51 of those have come over the past three years, according to the Center on National Security at Fordham Law School in New York. The center said the government secured convictions in 91 percent of those cases. Law enforcement officials say stings are a vital tactic for heading off terrorism. But civil rights activists and others say the FBI has been identifying individuals with radical views who, despite brash talk, might have little ability to launch attacks without the government's help. "It almost seems like the government is creating a theatrical event that produces more fear in the community," said Michael German, a senior policy counsel at the American Civil Liberties Union and a former FBI agent who worked undercover. Yet in these terrorism stings, every attempted defense that has alleged entrapment by the government has failed, according to Fordham's Center on National Security. The FBI said that record speaks volumes and rejected any suggestion that it has invented terrorist plots. "They present the idea," FBI spokesman Kathleen Wright said of the targets of investigations. It is not us coming up with these ideas.
