Many people put much more pressure on combinations of letters found in their own names than on the other letters they type. The fruits of this analysis are available, of course, only when documents have been questioned or found suspect and submitted to the laboratory.
This questioning is generally the obligation of the intelligence officer who first receives a document or of some staff analyst who finds that it does not fit well into the pattern of things already known about a case.
The decision to request technical aid for analysis of written materials connected with an operation has in retrospect often turned out to be the most important decision made during its course. The use of this facility for counterintelligence purposes has been a steadily growing thing, for every find encourages other intelligence officers to bring dead files back to life for comparison with the newly identified material.
Different areas have on numerous occasions found, when certain documents were compared, that they were host to the same adversary agent.
Many intelligence officers, however, still overlook the very evidence which might successfully terminate a case for them. It is often thought, for example, that a handwriting expert's services are necessary only when a document is suspected of being forged, whereas the results of expert examination may be much more far-reaching in identification cases.

Seven or eight years ago an intelligence officer came into possession, under circumstances which aroused his professional ardor, of a small scrap of notepaper bearing only an address and a very common first name scribbled underneath it. For two years he persisted in trying to identify the writer of this note, collecting handwriting.
In clandestine operations where secret writing is used as a means of communications, it is often advisable to have the developed secret writing, as well as the cover letter, checked in the questioned document laboratory against the possibility that the agent has been killed, captured, or doubled and his communications taken over by the adversary.
An earlier article in the Studies 2 showed the value of this procedure also for the purpose of assessing the agent's stability under strain. In order to obtain a maximum benefit from the laboratory analysis, the intelligence officer should exercise great care in collecting and preserving the documents he submits.
He should make every attempt to get samples of a suspect's handwriting without his knowledge-his signature on pay vouchers, for example, or reports or letters in his natural writing.
The highest quality of evidence is an uncontaminated original document. Anything less than that, such as a photocopy, is better than nothing, but still yields only qualified results. When it is known in advance that a document is to be submitted to the laboratory, it should be enclosed in a transparent plastic envelope large enough that folding is unnecessary.
