What is the benefit of conducting a field test at a crime scene?

Conducting a field test at a crime scene is crucial for the quick identification of substances present. This rapid analysis allows law enforcement officers to assess the situation more effectively, prioritize their response, and decide on the necessary actions to take based on the presence of certain materials or drugs.

For instance, if a substance suspected to be an illicit drug is identified quickly, officers can make informed decisions about the direction of their investigation, potential arrests, or the need for hazardous materials teams. Quick identification also aids in gathering evidence that can be critical for prosecution, as it helps establish connections to suspects or victims right at the scene.

The other potential benefits listed do not capture the primary objective of field testing, which is grounded in the immediate need for accurate and rapid forensic analysis.
