Care And Handling Of Documents
Do maintain consequential documents unfolded and in transparent plastic envelopes or evidence preservers.
Preservation of evidential handwriting in its original condition is of the utmost importance. He who carelessly mishandles documents of any class may preclude their accurate and complete interpretation.
No after-the-fact physical changes should be injected which could becloud an evaluation of an evidential handwriting or the document on which it appears.
