I don't think so. The coroner was simply following procedure. The manner of death was, in fact, homicide. It was not natural, accident, suicide, or, undetermined, the only other available categories. Although, if the category "suicide by cop" was available, I would not object. It does sound as if he was determined to die in a "blaze of glory". He obviously intended to take as many Americans and Jews - or best of all American Jews - with him as he could.
