Safety Considerations at Crime Scenes: Meth Labs

Prior to completing this week’s written assignment, review relevant materials and resources from CRJ 622 and CRJ 627, read Chapters 1, 5, and 14 in Dutelle (2016), complete required readings for the week, and watch the video Meth Lab Explosion In addition, please read the article Meth Lab Training for First Responders Finally, you must research at least three scholarly sources from the Ashford University Library relevant to this issue. You will use this information to determine the appropriate course of action and the reasons for those actions when encountering a methamphetamine lab.

Scenario

The police have received an urgent 911 call to respond to a home in an upscale neighborhood where a man was shot and is believed to be deceased. Police first-responders arrived on the scene and entered the home where they, in fact, found a deceased man. As they moved through the home to be sure that no one else was injured, and that the perpetrator was no longer on the premises, they found materials used to manufacture methamphetamine.

These materials included chemicals and containers, syringes, and empty boxes of pseudoephedrine. Consequently, at this scene, there was a death investigation and a drug lab investigation. Considering what you know about crime scene investigation based on your readings and research, write a three-to-four page paper in which you address the items listed below and support your responses with credible sources:

Examine the first thing the police officers should do when discovering a methamphetamine lab along with its importance.

• Analyze the inherent risks at a methamphetamine laboratory crime scene investigation.

• Evaluate the universal safety precautions that should be taken in this scenario.

• Analyze commonly accepted forensic and contemporary specialized techniques. Consider the following questions when composing your response: What is the level of personal protective equipment that you would recommend at this scene? Why do you think your recommendation is appropriate?

• Identify what, if any, specialized personnel could/should be involved in processing this particular crime scene and evaluate the value to the investigation.

To Certify or Not to Certify: The Issue of Mandatory Accreditation and Certification of Laboratories

According to the National Academy of Sciences 2009 report on improving the quality of forensic science in the United States, all forensic laboratories should be required to be accredited. After the report was issued, The Police Chief magazine called for mandatory accreditation in an article named The Need for Mandatory Accreditation and Certification (Links to an external site.)Links to an external site. (2009). Please read Chapters 2, 4, and 5 in the National Academy of Sciences 2009 (Links to an external site.)Links to an external site.report as well as the article and answer the following questions:

• What role does the forensic laboratory play in crime scene investigation?

• What is the difference between accreditation and certification?

• What is the role of each (accreditation and certification) in forensic laboratories and crime scene investigation?

• Based on your research into this issue, do you agree with the NAS (2009) and The Police Chief magazine position on mandatory forensic laboratory accreditation? Why or why not? Be sure to support your position with credible, scholarly evidence.

Forensic Identification: Science or Pseudoscience?

Crime scene management and investigation refers to the activity that goes on at an actual crime scene rather than in a forensics laboratory. However, the physical and trace evidence gathered in the field at a crime scene will eventually be analyzed in a forensics laboratory and the analyses conducted govern the types of evidence collected at a scene. Many individuals tend to accept as absolute truth that forensic laboratory testing and results are scientific in nature.

However, much criticism has been leveled in recent years that many of the techniques used have never been validated and no known error rates have been established. Without this information, we cannot be sure how often forensic examiners make errors in judgment or to what extent these errors are influenced by what the examiner already knows about the case. This has broad implications in criminal investigation.

For this week’s assignment, you will step out of the crime scene and into the forensics laboratory for a look at some known issues and criticisms in forensic laboratory testing as well as in credentialing someone to be classified as an “expert” forensic examiner. It is beneficial to understand what happens with the evidence collected at the crime scene once it goes to the laboratory.

Your research for this paper may cause you to question the reliability and validity of commonly relied upon forensic evidence in criminal trials. However, your job as a scholar (and criminal investigator) is to evaluate objectively what you are learning and arrive at a conclusion that is based on information from credible sources.
