Steve,
Well now, as an aspiring attorney, you know that I couldn't possibly say with 100% certainty that NO literature exists that provides the answer. I can only say that I did my very best in searching the INTERNET, and that no literature exists there.
However, as a law student you are probably as capable as I in searching. What you have then is just a second opinion. Perhaps what you need to do is hunker down at the local library and actually READ biographical books on Himmler.
Regarding the 9 bucks....I'm sure that you will make the right decision there too, based upon the facts that you've been presented with. And I'm certain that it won't be your only ethical decision to make in your career.
In any case, I wish you the very best in your studies. Please let me know how it plays out.
Best regards,
Michael
