In May, 2009, David Williams was arrested ... and hit with a 25-year jail sentence. Williams and three other struggling ... men beset by drug, criminal and mental health issues were convicted of an Islamic terrorist plot to blow up Jewish synagogues and shoot down military jets with missiles. Even more shocking was that the organisation, money, weapons and motivation for this plot did not come from real Islamic terrorists. It came from the FBI, and an informant paid to pose as a terrorist mastermind paying big bucks for help in carrying out an attack. Lawyers for the so-called Newburgh Four have now launched an appeal that will be held early next year. Advocates hope the case offers the best chance of exposing the issue of FBI entrapment" in terror cases. "We have as close to a legal entrapment case as I have ever seen," said Susanne Brody, who represents another Newburgh defendant, Onta Williams. "The target, the motive, the ideology and the plot were all led by the FBI," said Karen Greenberg, a law professor at Fordham University in New York, who specialises in studying the new FBI tactics. But the issue is one that stretches far beyond Newburgh. Critics say the FBI is running a sting operation across America, targeting - to a large extent - the Muslim community by luring people into fake terror plots.
