Historically firearm and toolmark examiners have rendered categorical or inconclusive opinions and eschewed probabilistic ones, especially in the United States. We suggest this practice may no longer be necessary or desirable, and outline an alternative approach that is within a comprehensive logical/Bayesian paradigm. Hypothetical forensic and non-forensic examples are provided for readers who are practicing firearm and toolmark examiners, and the strengths and weaknesses of both approaches are considered.
从历史上看，枪支和工具痕迹检验人员一直给出绝对肯定或无法得出结论的意见，而回避概率性意见，尤其是在美国。我们认为这种做法可能不再必要或可取，并概述了一种在全面的逻辑/贝叶斯范式内的替代方法。为从事枪支和工具痕迹检验工作的读者提供了假设的法医和非法医示例，并考虑了两种方法的优缺点。
