No Guest, I know nothing of this.
I would be surprised if there were no low level collusion.
I will be surprised if high level collusion is proved.
There may be persuasive evidence and important believers, but there is for aliens landing at Roswell, for no airliner hitting Pentagon, for the collapse of the towers being caused by explosives, for MI5 killing Diana, no moonlandings etc.
I think it may be another conspiracy theory.
If it is true I condemn it utterly and will be glad to see the guilty locked up.
If I had evidence i would give it to the police myself.
Sweeney, will you tell the police what you know about the murder of Jean McConville and other atrocities?
