Which is why Amaral was so suspicious when GM changed his story about which door he used to gain access to 5a.
If Gerry changing his statement about the doors was of any importance -
especially if it raised suspicions with the PJ - then surely the reason he gave for changing it would have been recorded in detail in his statement. On the other hand if the reason was to correct a misunderstanding by the PJ officer or the interpreter - then IMO that may be something which the PJ may not have been particularly inclined to advertise IMO.
However, there is no mention whatsoever of the reason Gerry gave - which imo Amaral has used to his own advantage in the same way he used the lack of a witness statement by JT to his own advantage when he wrongly claimed in his book that she had
''formally'' identified Murat as the man she saw on 3rd May. She did no such thing - but the reason why he could say that she did - was because there was no witness statement by JT to prove him wrong. Similarly - there is no witness statement from Gerry giving his reason for correcting his previous statement to prevent Amaral from inferring that his change of statement was suspicious.
