IT forensic reports allow investigators to gain insight into criminal offenses. They reveal immediately what initially does not seem obvious. Forensic analysis of computer systems can show whether data has been deleted from a hard drive, whether the documents generated on a computer are relevant for the criminal court or whether a criminal offense has been committed at all.
Furthermore, the IT forensic can often determine whether the offenses the accused was charged with were actually committed by the suspect or possibly even without his involvement by a third party. To this extent, IT forensics may help both to convict an accused person as well as to have an exonerating effect and clarify the circumstances under which the offense was committed.
