ou're the first responding officer at the crime scene. After providing any medical assistance and securing the crime scene, your next immediate task is to record and document the scene in its most original state. Your experience tells you that the scene contains many clues and may need to be described as it was found in court. Explain the reasons why recording and documenting must be done as soon as possible. Also, include how Locard's Exchange Principle impacts the work of documenting and processing the crime scene.

Answer the following questions:

1. How would you record a crime scene without a camera? What would be an advantage to videoing a crime scene and why or why not should narration while recording be included?
2. What type of items or clues are commonly exchanged at or from a crime scene? What types of items or clues would be different between a violent crime, a burglary, child pornography, and an auto theft?
3. How would you document a crime scene that has been tampered with?
