Can you cite the specific German statute or case history that says this? Or is it just what you intuitively expect to be true?

For what it's worth, I wish that were the case in the US too. But whether carrying a gun is illegal is a different question from whether using it in this specific situation makes you also guilty of the additional crime of murder.
It is a valid excuse in penal law, yet it does not apply to civil liabilities. You can still be sued for damages. An official prosecutor told me that you can use it once in your life to beat somebody up. After that, they will not believe you anymore.
However, I completely agree that it does not make sense to judge the Rittenhouse case by German law.
