A splendid illustration of what I think applied in the case of the Ripper. It is quite possible that he simply "got lucky" with Chapman, alhough (NB) not to the point of puncturing her colon and hacking through her bladder. The other evisceration murders might be seen as no less "lucky" in their own way. Whatever the degree of "luck" involved, there was little apparent "knowledge" on display, beyond that which a layman might easily acquire.
