I'll make it easy for you.
Your proposition is that Martin Smith changed his mind. So we can put three stakes in the ground.
You concur it was not before Jan 2008 ................stake 1
The process was live until July 2008 so it is unlikely to be before that otherwise he would have
notified the cops and it would be on file ................................................. stake 2
Oakley were elbowed in Aug 2008 ....................... stake 3.
Now if the Smiths took part in efits that were at the behest of Oakley it would have been between stakes 2 and 3 ie July/August 2008 which likely would also be when he changed his mind if your proposition is correct. Quite why he changed his mind (if indeed he did) is open to speculation.
So the efits were produced by end August 2008 (if by Oakley) and "were in the possession of the police" about September 2009, if we are to believe the Times apology. The force dealing with the case at that time was Leicestershire Constabulary, O.G not being in existence. Presumably The Met released the efits when O.G ceased to be a review and became an investigation which was roughly Q4 2013.
Make it easy?
Not so sure about that.
The facts:
At the end of January 2008, Mr Smith still believed he might have seen Gerry.
Mr Smith's wife (then!) also believed she might have seen Gerry.
None of Mr Smith's children (then as now) believed the same. (Mr Smith was honest enough to acknowledge the last point in his statement to Irish
Gardia police at the end of January).
At the end of January, Mr Smith was approached by Brian Kennedy, representing the McCanns, invited to produce an efit, but refused.
It is plain common sense that all the time Mr Smith believed he might have seen Gerry, he
would refuse (to produce an efit).
At some point between the end of January and the
Crimewatch programme, Mr Smith changed his mind and agreed to produce an e-fit, as did his wife who (we now know) produced the second efit.
Why did Martin Smith change his mind?
It can only have been because he no longer believes the man he and his family all saw that night was Gerry.
So the answer to the opening post (of this thread) is
yes!
