Document Examination (SWGDOC)

To determine whether or not handwritten items, one or more having a distorted appearance, are suitable for comparison.
2.1. This Guideline will be used as a continuation of the Guideline for the Examination of Handwritten Items, the Guideline for the Examination of Nonoriginal Handwritten Items, and the Guideline for the Examination of Exclusively Questioned Handwritten Items.
2.2. Terms defined in the glossary are in italics when they first appear in the Guideline.
2.3. A flowchart for this Guideline is in Appendix D.
That the forensic document examiner will have the following available:
3.1. A light source of sufficient intensity to distinguish fine detail.
3.2. An optical instrument capable of sufficient magnification to distinguish fine detail.
3.3. Sufficient time to complete the procedures of this Guideline.
4.1. Evaluate the apparent distortion in the writing. If appropriate, a comparison to other available writing may be made.
4.2. Determine whether or not it is possible to establish that the apparently distorted writing is natural writing.
4.2.1. If it is possible, and
220.127.116.11. It is natural writing, return to the
referring Guideline, or
18.104.22.168. It is not natural writing, proceed
to Section 4.3 in this Guideline, and continue.
4.2.2. If it is not possible, continue with this procedure.
4.3. Determine whether the apparently distorted writing is suitable for comparison. If it is, return to the referring Guideline. If it is not, continue with this Guideline.
4.4. Determine whether additional known writing would be of assistance.
4.4.1. If it would, request additional known writing.
22.214.171.124. If additional known writing is received, return to the referring Guideline and continue.
126.96.36.199. If additional known writing is not received, go to No Conclusion, Section 5.5 of the referring Guideline.
4.4.2. If not of assistance, go to No Conclusion, Section 5.5 of the referring Guideline.
