CSIs are responsible for which two steps in the admissibility of physical evidence for court?

The most appropriate steps that CSIs are responsible for in the admissibility of physical evidence for court are recognition and collection. Recognition involves identifying potential evidence at a crime scene and determining its relevance to the investigation. This is crucial as it sets the foundation for the entire evidence chain; if an item is not recognized as valuable evidence, it cannot be collected or used in court.

Following recognition, the collection of evidence must be done meticulously to ensure that it is not contaminated, altered, or damaged. Proper collection techniques are essential for maintaining the integrity of the evidence, as any mishandling can impact its admissibility in court. Together, these two steps are vital for ensuring that evidence is admissible and can withstand scrutiny during legal proceedings.

While other options include important aspects of crime scene investigation, they do not encapsulate the specific responsibilities related to ensuring evidence is admissible for court as clearly as recognition and collection do.
