The premis:  Israel is a pariah state: therefore any support group of questionable morality . The suggestion: A criminal underground of Jewish-Zionist bankers and politicians is in control, bumping off anyone who speaks out against the evil mother state.........yawn....... 

Ironically your reporters inadvertently blundered into a much more interesting subject - the (acknowledged) bias of BBC reporting - and it occurred to me that a programme on this subject would have been much more refreshing and engaging.  Hey, Channel 4 might even have taken the opportunity to expose the entrenched prejudice of their rivals, and soar above that moral swamp with a new, balaced and informed approach to Middel East coverage..... dream on.
