Can you help me understand this Social Science question?

There are several different types or classifications of evidence. Each type of evidence may have different requirements or methodology for handling them at the scene for it to be properly identified, documented, processed, and admissible at trial.Prior to beginning work on this discussion, please review the following:

• From the text:
  • Chapter 8: Pattern Evidence 1: General Patterns and Fingerprints
  • Chapter 9: Pattern Evidence 2: Firearms, Tool Marks and Document Analysis
• From the free, downloadable resource at the web page Crime Scene Investigation Guide (Links to an external site.):
  • Section D – Completing and Recording the Crime Scene Investigation
  • Section E – Crime Scene Equipment
• The articles:
  • An Automated Approach to the Classification of Impact Spatter and Cast-Off Bloodstain Patterns
  • Chemical Enhancement of Footwear Impressions in Blood Recovered from Cotton using Alginate Casts
• From the free PDF copy at the web page Strengthening Forensic Science in the United States: A Path Forward (2009) (Links to an external site.):
  • Section 10. Automated Fingerprint Identification Systems
  • Section 11. Homeland Security and Forensic Science
• From the video Bodies, Blood, and Ballistics: Forensics School, Part One:
  • Segment 2. Forensics: Blood Spatter 02:35
  • Segment 5. Blood Spatter and Trajectories 04:35
• From the video Hands-On Police Work: Forensics School, Part Two:
  • Segment 3. Crime Scene Photography 02:27
  • Segment 6. How to Capture and Record Fingerprints 03:10
  • Segment 8. Crime Scene Documentation 03:18
  • • Contrast the collection and packaging requirements for different types of evidence (e.g., digital, biological, trace, drugs, explosives, etc.)
    • Describe at least three different methods involved in the collection and packaging of evidence.
    • Contrast between these different collection and packaging methods to identify the type of evidence each is appropriate for.
    • Explain how the different types of collection and packaging of evidence might affect laboratory testing.
    • Explain the requirements for the collection and packaging of evidence related to admissibility at trial.

  Each thread must also address health and safety issues at the scene and in handling evidence (e.g., explosives, drugs, biological, etc.)The instructor has the discretion to reassign students to an alternative category to ensure all topics are covered.The body of your initial post should be at least 250 words in length. Support your claims with examples from this week’s required material(s) and/or other scholarly resources and properly cite any references. Remember science is objective, not a matter of subjective opinions.?
