Just because someone asks questions there's no obligation to answer them afaik. I'm discussing something that has occured and have no interest in unrelated speculations.
A poster in another place said,
"Some people are simply devoid of soul. No humanity at all, yet they walk among us. Destroying people is an elixir they drink for sport."If Brueckner is one such as those and German investigators have found that there is evidence that he harmed Madeleine - the German authorities have a duty to take their investigation as far as it will go.
There may have been no safeguards for Madeleine but Brueckner is safeguarded by the law of the land and enjoys the right to the presumption of innocence.
He is served by Lawyers who will see to it his rights are not breached under any circumstances by anyone.
My opinion is that lay persons who neither know or are entitled to know the case against him or the lawful strategy being used, would serve the interests of justice by allowing the investigation to run its course without let or hindrance.
While the rest of us await -
"Eager for resolution, terrified of the same."
