Final answer:
The statement that all items recovered from a crime scene must be sealed in air-tight, tamper-proof containers is false. Different types of evidence require different packaging methods to ensure their integrity, although all should be protected from tampering. The correct option is b.
Step-by-step explanation:
The statement is largely false because while it is essential that evidence is protected from contamination, the specific type of container will vary depending on the nature of the evidence.
For instance, certain biological materials might require breathable containers to prevent the growth of bacteria or mold which can degrade the sample, while other items may require air-tight seals to prevent the loss of volatile substances or to preserve fingerprints. The main goal is to maintain the integrity of the evidence which includes protecting it from being tampered with, either intentionally or accidentally.
Therefore, while some items may indeed be sealed in air-tight, tamper-proof containers, it is not a universal standard for all evidence. Professionals involved in crime scene investigation follow strict protocols to ensure that evidence is collected, stored, and transported in a manner that preserves its condition and prevents tampering or contamination.
Hence, Option b is correct.
