But at least letting him light the fuse or helping him to do so away from anyone else (after the plane has landed) would stop anyone innocent being injured. If he is so keen to blow himself up why let him live to try again another time when he may not be caught! After all the courts may release him in a few years time to try again.
Anyone who want's to kill innocent PAX deserves what he gets. I am sure his fellow PAX would have liked to deal with him when they landed!
