Some of the controversial "sting" operations "were proposed or led by informants", bordering on entrapment by law enforcement. Yet the courtroom obstacles to proving entrapment are significant, one of the reasons the stings persist.
The lengthy report, released on Monday by Human Rights Watch, raises questions about the US criminal justice system's ability to respect civil rights and due process in post-9/11 terrorism cases. It portrays a system that features not just the sting operations but secret evidence, anonymous juries, extensive pretrial detentions and convictions significantly removed from actual plots.
"In some cases the FBI may have created terrorists out of law-abiding individuals by suggesting the idea of taking terrorist action or encouraging the target to act," the report alleges.
