how can you produce an e fit of a face you admit you did not see
I don't place much store on the PJ reports, not because I have disrespect for the officers who took them, but because they were taken in reported form, delivered in one language, translated into another, then re-translated back into English and in the form we (finally) read on line.
I believe 'Watcher' on Amazon has the low-down on the technology that can be used for the production of efits as detailed as those produced by the Smiths.
How good it is (at enabling eye-witnesses to produce images that lead to identification of their subjects) I have no idea.
But Watcher suggests that's what they used.
She may be right.
I've no idea.
Perhaps the efits are, ultimately, not very useful (in helping to identify anyone named).
But they are the best shots, of an honest couple, both desperate to assist efforts to identify and nail the abductors of Madeleine, the best way they can.
We should applaud their efforts (I think) .....
