oh fgs, it's not as if the police beat Damian Green with rubber truncheons they followed procedure exactly as they should have, except possibly for the bit where the Serjeant claims they didn't tell her she could refuse the search (yeah right, what grown human being doesn't know the police need a warrant to search somewhere?)
If there's a regular, consistent, security breach from a sensitive government department and someone has been encouraging the breach and making it happen, I damn well want it investigated, whether it involves MPs or not. If the boot was on the other foot and the mole had shared dangerously damaging information with Al-Qaeda, wouldn't we all be calling for the police to do everything they could to find out where the leak was coming from?
The information leaked is wholly irrelevant - the crime Damian Green was accused of is aiding and abetting the sharing of highly sensitive information, which is punishable by life imprisonment.
As for the de Menezes case, this is quite a useful explanation:
"In his legal ruling to the jury before he sent them out to deliberate, Wright said they could not find the firearms officers who fired the fatal shots or senior officers coordinating the operation liable under criminal or civil law for the death because inquest law prohibited any jury returning a verdict that would lay the blame at the door of an individual or individuals.
He told the court he had listened to submissions from the legal teams for all the parties before making his decision. "After hearing the submissions the conclusion that I have come to is that the evidence in this case taken at its highest would not justify my leaving verdicts of unlawful killing to you," he said.
"This is so in respect of C12 and C2 concerning their direct involvement in shooting Mr De Menezes and also in respect of any of the particular senior officers in relation to their management and conduct of the operation."
Wright said the decision did not indicate police did nothing wrong on July 22 2005, but he said all interested persons agreed that a verdict of unlawful killing could only be considered if jurors could be sure a very serious crime, such as murder or manslaughter, had been committed to a criminal standard of proof, ie beyond all reasonable doubt.
Even if the jury concluded that a number of people made different mistakes which together resulted in the shooting of De Menezes, unlawful killing should also not be considered."
