Answer: In the five principles of investigation, I find confidentiality as the most easy to understand. I feel so that it is the most basic requirement of any investigation that confidentiality is maintained. It is no big logic to understand that for the safety of the witnesses and protection of evidences, confidentiality needs to be maintained. The processes and requirements of confidentiality are clear and so is the concept. The most challenging principle for me is of staying impartial during the investigation. Though it is essential for a fair trial that the investigator remains impartial but still many times the information related with crime can charge one with emotions. Emotional control is essential for remaining impartial which I feel that I lack. At times I am unable to understand that how one can remain impartial in certain situations. I therefore need to develop my skills and competencies for remaining impartial by gaining knowledge about the principle of impartiality. I will read academic literature and case studies related with this topic. I will also read about the strategies which can help an investigator to remain impartial and will apply them in practice.
