When evaluating forensic findings at the activity level, we place the results of an examination in the context of a criminal case. An expert assesses whether the results of an examination support one scenario to a certain extent more than another. This requires at least two scenarios.Usually, these scenarios will be put forward by the prosecution and the defence. Properly aligning these scenarios and/or the resulting hypotheses, the contextual information required for the evaluation, and any assumptions is crucial in such investigations, and therefore often a meticulous and time-consuming task.
