Scotland Yard: Injury From Blast Killed Bhutto

Re: Scotland Yard: Injury From Blast Killed Bhutto

I just have a question...haven't been following this situation too closely but I am confused about something. If she was shot; when she went to the hospital wouldn't the doctor that saw her know she had been shot? And if she was injured in the head wouldnt the doctor know that? I mean can't they use them as a source of witness???
