Abstract

MSP, relying in part on a paper by Morris [[5]], criticize DV use of I Cohen's Kappa i on several fronts: I Cohen's kappa i is "an inappropriate index of reliability...does not extend to multiple raters" ([ [1] ], p. 17). The Morris/MSP argument also, in a rather strange admission, suggests that, due to the material examined, a lower level of consistency is to be expected for firearms examination than most medical evaluations. The direct measures reported by MSP of repeatability, when averaged over bullets and cartridge cases using all five levels of the AFTE range, were 78.3% for known matches and 64.5% for known nonmatches ([[1]], p. 1).
