In bloodstain pattern analysis, pattern classification is the step in the method where the analyst evaluates the features of bloodstains to determine the potential mechanism of creation. The community has standard definitions for these different bloodstain patterns; however, classification is based on features, not definitions. This webinar guides the analyst through the process of establishing objective criteria for what features must be present to include specific pattern types within the pattern classification step. This will also include a discussion about embracing qualitative uncertainty in pattern classification.
