Something tells me it is not the “deceased’s honor” that is being protected here.
Terrorism? Or All in the Family?
I share your suspicions. In fact the mention of the word "honor" set off alarm bells. It isn't politically correct to mention this, but that woman and her husband are ethnically Arabs. Arab Jews that is - but Arabs in their culture. And anyway, in any culture, if a woman is killed in her home, she is usually killed by a family member - not in a mysterious "botched robbery" (is that a robbery where nothing is taken?)
If I were the investigating officer I would take a good hard look at the family of the murdered woman. The family have been allowed to forbid an autopsy, so they have made a successful prosecution all but impossible.
