My first thought was it was a security guard firing at the bomber.
I really couldn't tell if the gun was aimed at Bhutto.
I was wondering if I was the only one who didn't think at least some of the shots were aimed in her direction. I'm no expert but it looks like he could have been shooting at someone on a roof top.
Doesn't really matter if she was shot or died from the explosion. It was an assignation in either case.
