So are you saying that the Russian 'hit team' are still in this country then?
No. I'm simply saying the "leak", more than anything else, means pressure being applied to come up with something even if there is no basis to it in fact.
On 12th July, the head of the counter terror unit, Neil Basu, publicly stated they were no closer to finding who had done it. A mere week later, a "leak" through an unnamed source announces that they have found who did it. Then more "leaks" building on this since.
The leaks aren't real leaks - they aren't real whistle-blower type leaks. It is information/disinformation that some players want the public to believe, without having to issue official statements on the matter, so there is no repercussion to them if the information is discovered to be patently false, or if the narrative has to be altered. This is on top of using them to put pressure on all who are taking part in the decision making ("a discussion has begun between counter-terrorism officers, the Crown Prosecution Service, the Foreign Office, the Home Office and the intelligence agencies"), and making it easier for those who may have objections to just go along with it, if the current narrative flies with the public.
Three of those five agencies are known to have no interest in telling the truth. And the other two have some interest in truth and in justice but only if it doesn't rock the boat of which they are a part of.
I would suggest that any police who wish to find the real culprits would be well served to investigate the source of all these "leaks", who wishes to set a particular narrative regardless of the police findings or lack of them. But they won't keep their job if they do so. And there's always what happened to DS Nick Bailey.
