MM's case will be investigated as long as there is just cause for continuing with the investigation.Responding to a number of ideas here in one post.
Personally I don't think the prosecutor indicts cases in such a 9D chess way.
Rather he simply charges the cases that meet the legal standard to be charged. I am more suggesting if he does get the conviction on the HB charge and CB collects a long sentence for it, he can be reasonably happy with the practical outcome of going public, if not the optics.
The obligation put on prosecutors under German Law willl assure that and if at all possible MM's case will be taken to trial as a result.

'Legalitatsprinzip, the German Rule of Compulsory Prosecution. Under this concept, the prosecutor is forbidden to refuse to prosecute in felonies and misdemeanours where there exists sufficient factual basis or probable cause to proceed.
