All everybody has got to remember is that crime scene photograph No.23 was taken on the strip of negatives bearing the serial No.0012, and that crime scene photographs, 25, 26, 27, 28, 29, 30, 31 and 32, were taken using the negative strip bearing the serial No. 0034...
During the trial, Bird and Cook lied by informing the court that photograph 23 was taken 'after' photographs, 25, 26, 27, 28, 29, 30, 31 and 32...
But...
on 31st January, 2001, PC Bird made a witness statement to COLP stating that he had stated that the photographs taken with use of negative strip 0034 had been taken 'before' photographs taken by negative strip 0012, which, 'he admitted' was 'incorrect'. He re-affirmed that photographs relating to negative strip 0012 had been taken before photographs taken with use of negative strip 0034...
Bingo!!!!!
