insight?

can anyone enlighten me as to the relevance of the possibility that benazir bhutto died from hitting her head? if she did, is that supposed to exonerate someone or some entity? i can't seem to figure out the implications of this new revelation and yet, no one will elaborate to enlighten me... at least no one on the radio. i suppose i could search out more text for the answer, but maybe someone reading this will know, so i'll check here first.

i mean, they couldn't possibly be implying that the entire death was an accident... an unfortunate slip and fall.
they couldn't possibly be implying that more security would have been pointless because... well... i don't know... i'm not an expert in security, but isn't security supposed to keep guns and bombs at bay, so that the immediate results of these things (i.e. impact... be it from actual shrapnel or shrapnel-less force) don't happen? i don't see how they could be implying exoneration and yet i can't seem to think of any other reason this would be an issue.

lest i'm being just as ambiguous: the person who attempts murder, thinks they've accomplished it (when in reality they have not), takes that person out to a ditch to rid themselves of the body, in the middle of winter... and the person in fact dies of exposure to the elements... well, they've still caused that person's death, just not in the manner they supposed. still, they could be found guilty of murder, rather than simply attempted murder.

i could be way off on a tangent and not know it because there could very possibly be some other reason it is (seemingly) such a big deal that she died of a skull fracture and not a bullet or shrapnel, so if you know, please share!
