When it gets so bad that the presumably (but not, on this evidence, demonstrably) learned Gp Capt Alistair McGrigor has to come out with a line that will doubtless be quoted in lawyers' line books for years to come:
"If you take away the eye-witnesses, there is no evidence that the ac were seen to the east of Ben McDui. Isn’t that true?"
It is probably time to accept that not all is well and either something very fishy has gone on (conspiracy theory) or the (more likely) rank incompetence of the prosecuting authorities is demonstrated (cock-up).
