The court appears to believe the claim that her death was accidental. I don’t doubt that he had no intentions of killing his daughter.

If you don't have inside knowledge on the case, "not having doubt" on either intentions or no intentions is an incredibly moronic take.

Also, the job of a court of law is to establish innocence or guilt (and the degree thereof). This grand jury failing to indict is that grand jury refusing to do its duty to the people. While Germany is also going to shits, I am kinda glad that for now, our country is civilised enough to not have juries. Although we have the next worst thing, which is laypeople judges, for some cases.
