The _______ and _________ in which evidence is collected should be left up to the investigator.

The correct response focuses on the importance of allowing investigators the discretion to choose how they handle evidence collection. The terms "method" and "manner" are particularly relevant as they encompass the procedures and techniques that can be employed in gathering evidence.

"Method" refers to the specific techniques or approaches used during the evidence collection process, such as whether to use physical tools, digital devices, or specialized equipment. This can vary depending on the type of evidence being collected and the circumstances surrounding the investigation.

"Manner," on the other hand, describes the overall approach or style in which the evidence is gathered. This could involve considerations such as the level of care taken, the protocols followed, and the investigator’s judgment in the field.

By giving investigators the autonomy to decide the method and manner of evidence collection, it respects their expertise and allows them to adapt their strategies based on the unique factors of each situation, which is crucial for ensuring the integrity and validity of the evidence collected.
