Criminal investigation refers to the effort put to uncover information related to a crime. Criminal investigation undertakes to determine if a crime has taken place or whether a suspect has committed.
Criminal investigations are essential because they lay the foundation for the rule of law. For the rule of law to prevail, facts regarding a crime must be established. Moreover, there are circumstances surrounding crimes that may implicate people who are not criminals. Without criminal investigations, people who are wrongly accused may be convicted and jailed for crimes they did not commit.
Criminal investigation serves several purposes. The first purpose served by criminal investigation is to probe reports or information indicating that a crime might have been committed. The second purpose of criminal investigation is to collect, uncover and preserve evidence collected regarding a crime. Moreover, criminal investigation is responsible for establishing whether there are sufficient reasons that can warrant prosecution of suspects involved in a criminal offense (Clark, 2006). The criminal investigation is responsible for establishing whether a criminal can be identified with regard to crimes.
The practice of criminal investigation is not a new phenomenon and has been in existence for many years. In the bible, the concept of criminal investigations has been highlighted in several texts. One such text is found in Deuteronomy 19:18, where the law directs the judges to investigate cases brought to them expeditiously in an attempt to establish the truth and avoid injustices. The text was meant to protect the accused against false information from witnesses. This text is important to me because it illustrates the importance of establishing the truth regarding crimes even from a religious perspective. I picked the text to demonstrate that the criminal investigation is founded on values of justice and is not a mere procedure established by modern legal systems.
