I'm not offended or worried, what strange ideas. If I thought that Operation Grange were following productive lines of investigation I would be very pleased, but they have been credited with imminent success too many times for me to have much faith in their abilities. I can't assess the PJ investigation as they have very wisely kept their activities to themselves.
Quite obviously you think you know more about operational matters than Scotland Yard do. Bearing in mind that they have obviously asked for and received more funding to pursue whatever and whoever they are in the process of investigating.
Madeleine McCann was a child ... a young person now if she has survived ... who the police stopped looking for as we now know a few months after her disappearance, the focus of the investigative strategy becoming her parents.
Of those 'other missing children' who have not received home office funding 'like Madeleine McCann', which one had a case conducted as Madeleine's was? Which one was written off as being dead without evidence? Which one of them had his/her case halted before all investigative opportunities had been carried through to conclusion? Which one's parents had to employ private detectives because the police were not doing their job?
Madeleine McCann is only now receiving attention commensurate with the enormity of the crime carried out against her.
If the police are forced to close down the investigation, in common with the parents of 'all the other missing children' the McCanns will know that all was done that could be done.
That was denied her in 2007.
