They lie ...do things for money...so how on earth can you make them credible.
It is strange how one's standards drop when it suits an agenda it seems.
He took photographs of his girlfriend's daughter as part of his abuse of her.
The Germans are investigating if he is involved in the rape of the Irish woman who recognised the MO being used by Brueckner during the rape of the American woman.
Both women were filmed.
Brueckner has an interest in collecting video and photos whether filmed first hand or downloaded as detailed in the cache found by the German police.
What details are given to the police by his fellow miscreants will be disregarded unless there is evidence which fits it into the jig saw of evidence the German police are putting together.
I think the Germans are being very thorough in their collection of evidence but as you can see they have plenty to be going on with. There is no need to rush Madeleine's case while they sort through other cases for example the ten year old accosted on the beach which should have been dealt with at the least even if not solved at the time by the Portuguese police.
I don't think the Portuguese police record of dealing with offenses against women and children, mainly girls, is a particularly good one.
