Forensic Linguistics Tour
The left hand picture shows a word produced by OPTICAL CHARACTER RECOGNITION (OCR) software in a particular document which had been scanned by an alleged forger.
The right hand image shows the word as it had appeared in the original document (which was then altered in some important respects by the individual concerned). As trivial as this small piece of evidence may seem it was instrumental in demonstrating the likelihood of forgery in a particular case given the nature of the alterations and how they were misinterpreted in a later scanning procedure.
