They have both been looked for.
'Drs McCann being "too sensitive" they have been seriously let down by the forces of law and order who have allowed'

It is the mccanns who let down their children, not the forces of law and order.
Both cases remain unsolved.
FACT.
Why don't you get down off your hobby horse of parental culpability and for once deal with the subject of the thread which wonders if the Drs McCann are being a tad sensitive to the lies, hatred and innuendo directed at them and their daughter.
They are maligned and abused not by one stalker ... which can be so bad that people have committed suicide as a result ... but by a coterie.
There is probably not a
minute ... second of every day that dawns that somewhere in the world someone is not sitting at a grubby keyboard typing grubby lies about them.
Why do these people do that? It is beyond my comprehension that there are people who think that may not be damaging, particularly since that is the object of the exercise, and who think it odd that the target of the lies should be less than happy about it.
