[img]http://claim Edit Dr. Martin Fackler, a Vietnam-era trauma surgeon, wound ballistics researcher, a Colonel in the U.S. Army and the head of the Wound Ballistics Laboratory for the U.S. Army’s Medical Training Center, Letterman Institute, claimed that hydrostatic shock had been disproved and that the assertion that a pressure wave plays a role in injury or incapacitation is a myth.[6] Others expressed similar views.[17][18] Dr. Fackler based his argument on the lithotriptor, a tool commonly used to break up kidney stones. The lithotriptor uses sonic pressure waves which are stronger than those caused by most handgun bullets,[citation needed] yet it produces no damage to soft tissues whatsoever. Hence, Fackler argued, ballistic pressure waves cannot damage tissue either.[19] Dr. Fackler claimed that a study of rifle bullet wounds in Vietnam (Wound Data and Munitions Effectiveness Team) found “no cases of bones being broken, or major vessels torn, that were not hit by the penetrating bullet. In only two cases, an organ that was not hit (but was within a few cm of the projectile path), suffered some disruption.” Dr. Fackler cited a personal communication with R. F. Bellamy.[6] However, Bellamy’s published findings the following year[20] estimated that 10% of fractures in the data set might be due to indirect injuries, and one specific case is described in detail (pp. 153–154). In addition, the published analysis documents five instances of abdominal wounding in cases where the bullet did not penetrate the abdominal cavity (pp. 149–152), a case of lung contusion resulting from a hit to the shoulder (pp. 146–149), and a case of indirect effects on the central nervous system (p. 155). Fackler's critics argue that Fackler's evidence does not contradict distant injuries, as Fackler claimed, but the WDMET data from Vietnam actually provides supporting evidence for it.[20][21] A summary of the debate was published in 2009 as part of a Historical Overview of Wound Ballistics Research.[/img]
