Evan Marshall and Ed Sanow rocked the firearms world with the release of Handgun Stopping Power and Street Stoppers. Both books predicted the effectiveness and that were on the right track 40 +/- years ago.
The Marshall Sanow one-shot stop percentages are nonsense because they deliberately exclude situations when one shot was not enough to stop someone and additional shots had to be fired.
Successes are meaningless unless you factor in failures. And Marshall & Sanow's numbers do not factor in situations when one shot was not enough, therefore they have no meaning.
Further, many agencies who Marshall and Sanow claim to have gotten their shootings from have come forward and said that not only did they not provide any information to Marshall & Sanow, and that the shootings that Marshall and Sanow have attributed to them do not match any of the shootings that they have on record.
The July 1992 Law and Order Magazine has several letters to the editor, as well as a statement by the magazines’ editor, further illustrating the lack of truth and serious errors in the Marshall and Sanow's “data”. Several papers have been published in the peer reviewed IWBA Wound Ballistics Review which have discussed the lack of credibility of Marshall and Sanow. The review wrote that "It was clear in our review and in from the investigations by others that Marshall & Sanow had lied, fabricated data, and did not follow scientific protocols. Their information is fraudulent and meaningless. Please do not stake your life on this garbage.”
Their work has been refuted by the International Wound Ballistics Association.
