And Now The Good News.

In this country, some people are not especially a part of one group or another.
Like democratic 'loyalties', the authority of the 'powers that be' is divided and largely concensual; a man may do the bidding of the spiders, one day but not the next.
Obviously the closer he is to the centre (knowingly) then the more likely he is to be a life-thrall.
And then there are the many who have nothing to do with this. To their knowledge.

Also, there may well be many groups of these people at many levels, in continually shifting alliance, neutrality and emnity, mainly neutrality, as envisioned by Bismark and his system of dependencies and threats.

When Mohammed Al Fayed suggests that 'MI6', the Secret Intelligence Service, was responsible for the deaths in Paris, I believe that he is guilty of gross over-simplification.
What do we know about MI6? Not a lot. Except that the pattern I described is largely consistent in that they do use people who are, literally, agents, which means that there are people doing their work who do not possess a FO Civil Service Pension or holiday benefits, but who do, let us say, find certain things in British domestic life a little easier.
If they need 'muscle' they call on something they refer to as 'the Increment', a collection (rather than a unit)of well qualified and experienced military men. And probably women too if SOE was anything like.
But the point is this.
Living in vagueness may be an effective method for hiding a political executive arm in open view, but there must be many, temporarily non-current, retired and 'wannabe' fairly-secrets, hovering around the action(especially the lack of it), like Fruit Flies around a Whiskey Bottle.

These are the sort of people who would murder Thomas A-Beckett to gain the approval of the King, or shoot a rival gang-member to gain peer-approval, or generally try to make a 'name' for themselves in (fairly) secret circles.

Of course, the actual MI6 will regard these fruit-flies with contempt and amusement, except where they actually join a serious power bloc which potentially poses a threat. (But not internally- MI5 is the one with the motto 'Regnum Defende').

Trouble is, and precisely because their antics are allowed, tolerated and possibly even encouraged(as cover),the flies get drunk on the irresponsibility of their living lie, and try to convince the many, many, all too gullible public around them that they are the genuine article.

And so, two men and a dog(a fairly secret dog) can all too easily wield intimidatory 'power' over a swathe of people. And these dupes become, in turn, their agents.
?Just look at the case of the fraudster who stole a million by pretending to be from MI5. He almost founded a cult-and a cult of secrecy is what allowed him to do it for years.
(But he is now in prison).
So. Maybe MI6 killed the man who crashed into Diana. But not Diana. And they probably are obliged to flex their muscle like that, occasionally, to keep these fuckworts in their places.
But know this-they don't operate in the UK without Secretarial approval, and the ones that do-MI5-don't have any legal executive powers.

Which brings me back to the main subject:power blocs. The summary is that no single group rules the social roost( hence the term 'concensus', whether or not political), and most of life is unaffected-they only penetrate or go active for specific reasons.
They may pursue specific people.
They may defend specific people.
But if they go for the test of Law, in public, these people are on their own.
