Private investigators are constrained by many limitations.
I remember reading something from one of the private investigators saying that they were watched and they had to hand any information to the PJ. I'll try and find it.
On Sunday 27 October 2013, just 13 days after that BBC Crimewatch McCann Special which brought the Smithman e-fits of two quite different-looking people to the notice of 7 million British TV viewers, the
Sunday Times pointed out (correctly as it happens) that these two efits (despite the apparently crucial significance now attributed to them) had remained under wraps for five-and-a-half years.
Although no date has ever been given for exactly when they were produced, the consensus of opinion is that they were produced - by Henri Exton - in the spring of 2008.
Unfortunately for the
Sunday Times, their report carried the implication that the
McCanns were responsible for this delay of over five years.
Not for the first time, the McCanns reached for their lawyers.
A few weeks later, the
Sunday Times printed a grovelling apology, conceding that the
McCanns had passed the efits
'to the PJ and Leicestershire police' -
'by' October 2008.
This raised a number of questions, e.g.
1. On what actual date were these efits passed by the McCanns to the PJ and Leicestershire Police?,
2. Why did the McCanns not immediately hand these two efits to the PJ and Lesicestershire Police, instead of waiting for several months?, and
3. Why did the PJ and Leicestershire Police sit on these oh-so-crucial efits for a whole five years (October 2008 to October 2013)?
[ IIRC the
Sunday Times had to pay out £35,000 plus costs to the McCanns for their error, in addition to a prominent publication of their apology in their newspaper ]
