I don't have any issues, thank you, I was highlighting what I see as yours.
I think that suggesting that the BKA has plenty of evidence is a triumph of hope over fact. Operation Grange aren't accepting the word of the Germans it seems. Until they see definitive evidence that Brueckner abducted and killed Madeleine they are still investigating a missing person case. They are said to be stopping soon too, although they haven't said why.
Nor have they said they are stopping and you are placing a great deal of faith and hope in unattributed tabloid intimation that they are.
The point is that if Operation Grange do not require further funding it means there are no further investigative opportunities or suspects to be followed.
Brueckner is not only the BKA prime suspect; SY have been investigating him for at least as long and he is their prime suspect too.
Were I you I would cast my eye in the direction that SY have gone as far as they can go and consider the case over all bar the shouting and for you to hope that there is sufficient evidence to bring Madeleine's case to trial and a definitive closure.
After all isn't that what sceptics are allegedly all about ~
JUSTICE for MADELEINE ~ real justice which doesn't come with a sceptic caveat.
