Rigby's tragic murder illustrated how easy it is for terrorists to commit an outrage. Two very disorganised Nigerian nutters murdered him with knives. Unfortunately, if a couple of nutters decide to go at someone on the street, they have a high chance of success.
Which is why you would have to be a lunatic actually to believe MI5's repeated claims during the last decade that there are thousands of dedicated terrorists out there, fanatical determined and organised, but in a decade of constant effort they have succeeded in killing nobody else. There were, MI5 claim, six actual terrorist plots this year but fortunately MI5 saved all of us.
If you believe MI5's stories, there are two possibilities. The first is that we have security services of a quite incredible efficiency, able to foil random terrorism, generally regarded as near impossible. The second is that we have thousands of dedicated terrorists of such incredible ineptitude that they can't manage to kill anybody, even when they could choose any random undefended target in the entire UK and any method from knives to poison to hit and run to shooting to bombs, and don't mind losing their own lives in the attempt. We have rubbish terrorists.
Comment: From the Wikipedia page of the Oxford 'society' that Cameron apparently did this for, we read: We're reminded of the initiation rituals to the all-male 'Skull and Bones' cult at Yale University that the Bushes and John Kerry were members of.
While #PigGate is producing some hilarious reactions among the British public, let's not forget that the debauchery practised by Cameron and his kind are indicative of the psychology of those in power. The cost, to them, of wearing a 'mask of sanity', as psychologist Harvey Cleckley termed it, is that they must regularly take 'vacations into filth' to relieve themselves of the 'burden'- from their perspective - of pretending to be human.
Regarding the initiation rituals of various 'elites', they serve the purpose of 'binding' them to secret societies, clubs and cults that both reward and control their subjects over the course of their future careers. It may be worth considering whether this information is being made public now in order to exert pressure on Cameron and his government; a little reminder, perhaps, that 'we can destroy you'...
