Which of the following is a downside to using storage boxes for evidence?

Using storage boxes for evidence has the potential downside of improperly secured boxes may compromise the integrity of the evidence. Evidence collection and preservation are critical components of the criminal justice process, and maintaining the integrity of evidence is essential to ensure it is admissible in court. If a storage box is not properly secured, it can lead to contamination, loss, or tampering of the evidence contained within.

Considerations related to the other choices include their impracticality compared to the correct answer. While cost may be a factor, it is not universally the case that storage boxes are expensive; there are many options available at varying price points. Similarly, while transporting certain heavy or large boxes can pose challenges, most storage solutions are designed for mobility. Lastly, while some boxes may not be suitable for specific types of evidence, many storage options can accommodate a wide range of evidence types when properly selected and used. Thus, the most critical concern remains the security and integrity of the evidence itself, which is effectively highlighted by the correct answer.
