You do know it wasn't written by Wilkins, of course? Like the PJ interviews he talked and the police wrote.
From the hand writing I believe it is Jez. London police - how could this be proved, who should initial the cross outs if the errors were made by the police officer? All the minor corrections are initialled by JW so in my understanding that is Jez who did that. Even though I did wonder why Jez would spell his kids and wife's name incorrectly.
OK so you think this is a verbal statement written by the police. How can we prove that?
I see some corrections are initialled PR the policeman's initial, and the 7s are written differently eg the date is probably written by Jez (signed and dated. the policeman may have dated it). But none of the other "r"s in the text are like the PR of the policeman's hand writing.
On the bottom of the page the policeman signs his signature and you see his style and it is different to Jez' hand writing. The P of Praia da Luz and the P of his signature are distinctly different.
