If questioning on the scene is performed correctly, however it – recalls the memories of a person – seems to be a human data source, we need to lay down, it is more than that. In those cases, when we get uniqe informations, which are only known by the people who were there at the crime, and the previous inspections are reinforcing about it with material evidences, and it reflects on the spot, then it is a material reflection of a special personal evidence. In these case, we think, the material reflection of a special (unique) personal evidence produces a new, combinated evidence.
If our thread is correct, we think, we need to rethink categorizing questioning on the scene as a personal evidence. By the introducing it is clear to see, that this procedural act has a personal nature, but its role mutated by the material reflections, its effect is unquestionable.
