"Suspected"/ Based on what evidence? Clearly none because the shin bet did not present a strong case for the courts to back them up. Or let me guess, the court is either anti-semitic or a self hating jew, or in fact has connections to terrorist elements itself does it? You only act if you have some evidence, this action was done on a personal bias of the interrogator and nothing else apparently.
