In a half hour television crime show the criminal is easily caught and properly punished. But that is not reality of law enforcement investigators. Although there is a science of investigation taught to all police officers at the Police Academy, the actual mastery of criminal investigation skills, is not learned from any book but instead by first-hand experience. It is also true that individual investigators have skills, abilities and proclivities in one area or another, and each investigator has their own personal background of cases they have investigated. There is a great deal of tedious labor of the investigation of a crime including a crime scene search, interviews, tracing, identification, interrogation, assembling of proof, and the presentation of testimony. The criminals are also very ingenious and are constantly devising new patterns of crime. To this constantly changing landscape of criminal endeavor, the investigator applies time-proven principles and techniques to the endless assortment of situations that confront him. The field of criminal investigation is as broad and varied as is the medical field and law enforcement officers and agents become specialized in particular areas of crime, such as drug enforcement, governmental corruption, white collar crime, and civil rights enforcement. Just as the end result of a doctors’ diagnostic tests and clinical examination is a final definitive diagnosis and treatment plan, the end result of an investigation is competent evidence that can be used in court and a plan for prosecuting the criminal offender. The Prosecuting Attorney judges whether the police investigation has been thorough in all respects or whether further work remains to be done. The evidence provided to the prosecuting attorney will only be as good as the investigators who gathered it. There is nothing that the Prosecuting Attorney can say or do that will retrieve that which has been overlooked, improperly obtained, or carelessly handled. Many a case has been lost at the crime scene rather than in the courtroom. There are many cases that have never reached prosecution simply because the investigator was unable to produce sufficient admissible evidence. To the Medical Whistleblower, the competent investigator who is well versed in his professional skills and who searches for every shred of evidence, applies his training resourcefully, and handles his suspects with restraint is asset of incalculable value to the attainment of justice.
