Hi Roman,
you are completly right, that Dr. Walzl put only guesswork from hearsay.
Yes, sentence of his statement is such, that it is possibility, that his own man killed him.
But on the other hand, he knew, that somewhere in Literature (which he want not to mention in the Book) is statement with some sources who killed Wirth.
He knew exactly the Unit, which should killed him.
As a Historian, he must tell us, what is wrong with this sources before he as specialist decide for roumors.
It was enough to say, that sources for "Istrski odred" are not trustworthy and that some members of "Einheit R" said in interrogation procedure before German judge, that could some member of "Einheit R" killed Wirth.
I was suprised, that well known Historian instead to balance sources decide for roumors, thats all.
But I understand, that the Historians has a big gap with the works of slovenian Historian because of language. As for instance have a problem with english or german language.
