Polygraphs Roles in Detection Physically and Mentally on Suspects - Research Paper Example Victims of sexual assault may not be able to justify the events that led to the assault thus calling for the use of the polygraph on the perpetrators in order, to tell the truth regarding such events. In criminal investigations, the perpetrators are bound to display various post-traumatic stress disorders such as anxiety and other emotional attributes that help the polygraph to detect the truth on a certain matter with ease (Rathus, 2010). The use of polygraphs has been employed by many prosecutors in the court of law to justify the truth on the case in the litigation, which helps to the criminal investigation. The polygraph is used in the military interrogations whereby the examiner of the polygraph detects the truth concerning the military information from a suspect. The polygraph may extend its purpose to the military personnel in order to assist them in to detect a post-traumatic stress disorder that may affect their emotions and behaviors especially after a combat in battles. A suspect holding military information is treated as a threat especially when such an individual is not in the discipline forces, which, therefore, requires the use of the polygraph in order to unravel the truth of such information. Military personnel is subjected to post-traumatic stress disorders after a series of combat, which, therefore, calls for the use of the polygraph in order to assist such a person in dealing with emotional and behavioral changes that follow major combats. The polygraphs enable an examiner to identify the emotional and behavioral changes that befall a military personnel thus helping the examiner to address the challenging issues, which subsequently enables the military personnel to cope with any post-traumatic stress disorders.
