Who fired the other 4 shots?
Joseph Wambaugh believed it was Smith yet the movie portrays him as much less cold-blooded and calculating individual than Powell (although perhaps James Woods' commanding performance helps to make him seem so intimidating!) The director is non-committal, the shooting scene is deliberately ambiguous.
Smith maintains that he is a petty thief and not a killer. I haven't read the book.
Just wondering if either Smith (death-bed confession?) or Powell have ever made any subsequent admission about who fired the 4 shots into Campbell's chest as he lay on the ground?
