It was a display of how deliberately ruthless, lethal and at the same time utterly incompetent the system they had put in place was (and indeed still is) and I speak from experience, having been surrounded myself by a team of armed police marksmen with a helicopter thudding above my head and been entirely innocent of any wrongdoing whatsoever. On their past form: Harry Stanley, Menezes... I seriously thought at that moment that my number could be up.
That sounds pretty bad; sorry to hear it. It doesn't apply as any kind of evidence in this case, though. deliberately ruthless, lethal and at the same time utterly incompetent
Also, this is stretching it more than a bit. Those characteristics seem pretty discrete to me, rather than obvious corollary. Would you describe an Iraeli soldier shooting a Palestinian in the eye as 'ruthless, lethal and incompetent'? They are not contiguous.
Dick rose because she had been earmarked and had been previously groomed for high places before the Menezes debacle: lots of "accelerated promotion" for the accountancy manager with impeccable Oxbridge connections; female... lesbian: she ticked all the necessary elite middle class plus many of the 'diversity' boxes on a political level; The mess she made wasn't going to be allowed to override that.
No doubt she was earmarked for high rank - she'd already attained that, so qed; the rest I think is pure supposition, and pretty stretched again, when you consider the circumstances.
I've offered little more than supposition (opinion) myself, but from a study of the known facts, I've come to a different conclusion. Because as far as I can see, the facts support the idea that the operation (to kill Jean Charles) was a success.
I know you won't agree and fair do. I will maintain that the logic - as far as I understand logic - favours my view.
