What everybody who is not in the know needs to know, is that it doesn't matter what is written in a witness statement, what really matters is whether or not the witness attends court, takes an oath, testifiea, standa up to cross examination, and that at the end of the day, the witness stood up to the legal requirement stipulated in the citation on the first page of each and every witness statement - "I make this witness statement of my own free will consisting of X pages, knowing that if it is tended into evidence, I ahall be liable to prosecution if I have wilfully stated anything I know not to be true, or false"..
Now, I take issue that many prosecution witnesses in almost every case do not make thier own witness statements. Invariably, Somebody else makes the statement for them, paraphrasing answers to questions that have been asked, without any reference to how the answers have been obtained before the answers themselves have become paraphrased...
I can't see how a witness whose witness statement has been tended into evidence, in these circumstances, does not commit a criminal offence, and why they are not prosecuted more often..
The defence very rarely get to see, the many variations of a typed witness statement, because it would then be blatently obvious that the contents had been worded and paraphrased by someone else. This has occured in the instant case, many different versions of relatives witness statements have been produced by someone else, were not disclosed to the defence so that the witness could be questioned about thier content...
