I cannot say how important professional ethics are in the Criminal Justice profession. In everything we do as Board Certified Criminal Defense Investigators, we must remain neutral, and free from bias when conducting research and investigation in the field, especially in areas like investigation were confirmation bias happens regularly. Defense Investigators, and Criminal Investigators especially, must be aware of the bias that can occur when an investigator comes into a case with preconceived notions and opinions. This causes the investigator or researcher to search for evidence to support the theory instead of a search for the truth. In criminal Defense Cases I have worked it was additional information that we may have uncovered through the investigative case review and analysis that brought this type of investigative police work to light.
