When you are proving that you were deffo fitted up, it makes the whole job harder because of the people who then get into trouble over your fit up!
I have paraphrased Paddy here. But he does have a point. How on earth do the authorities contemplate dealing with a fit up of the magnitude of the Bamber case? How on earth do they admit to the British public that numerous others of good standing, from an ACC downwards, had some involvement. Or that the DPP attempted to obstruct the release of even the
edited logs? Or that there is no evidence trail for the main prosecution exhibit that corresponds to when it was supposedly found / tested?
In this climate of financial cuts also. 'We cant afford a scandal' takes on a monetary meaning.
I think Paddy is referring to obdurate obstructions. A brick wall. A wall of silence. A wall of excuses. A wall of fobbing off. A wall of delays. A wall of passing the buck. A wall of lies.
