Keith, I don't believe the McCartney's got it wrong. There again, it depends what you mean by "kill". The ranking person in question may not have actually stabbed Robert McCartney, beat him with a sewer rod, or kicked him in the head, but he was certainly there and played a major role in the murder. Such was his self-image that he asked Mr. McCartney: "Do you know who I am."

I suspect that just about everyone in the bar knew who he was. Hence the deafening silence.
