Because the Jugendamt is involved...
Why do you assume all is peachy? Because the father is polish??
There are millions of polish-german families where there is no problem whatsoever...so don't try
to sell me the Jugendamt hunts poor Poles down and wants to steal their half-german children for sport!
If there serious probability of that happening, there should have provided interpretor or recorded what he was saying
That's what they are doing....the no-polish action is taken only when they can't provide a polish speaking/understanding social worker.
And recording sexual abuse or threats is a tad..erm...to late!
Its not for the institution to arbitrary decide in what language parents are allowed to speaking to their children.
Normally not, but that wasn't an normal case. The man could only meet his children under supervision, the mother has the sole rights, so this case has a background which doesn't look so good for the father.
And if the suspicion is so great that the social worker need to understand what he is talking then you should wonder why that is.
If I were the father and meeting the children would be all what counts for me because I love them so much. Using german
(that I know for 30 years and even teach) with my half german children would be the last on my mind.
But instead he makes a case out of it...strengthening all the suspicions about this man I might have, sorry!
He doesn't seem to care about his children or meeting them at all, only that he can speak with them in a language nobody else can understand... WONDER F*UCKING WHY!!!
What the heck does he want to tell them nobody else should know???
