(11.01.) Editor‘s note: This story is adapted from The Terror Factory, Trevor Aaronson‘s new book documenting how the Federal Bureau of Investigation has built a vast network of informants to infiltrate Muslim communities and, in some cases, cultivate phony terrorist plots. The book grew from Aaronson‘s award-winning Mother Jones cover story „The Informants“ and his research in the Investigative Reporting Program at the University of California-Berkeley.
