What is the error margin of your signature analysis?

Using a practical example, we present advantages of the approach we have chosen to assess our results and show that a logical approach for evidence evaluation can be followed even in a forensic discipline where no tabulated data are available. This example also illustrates a practical way of addressing the error margin question, which helps the Court understand what can be the risk of being wrong in this particular case (and not in cases in general). We further present the way these results were communicated to the fact finders in the case at hand and provide guidance as how forensic observations can logically be combined with the other elements of the case.
