Which of the following does NOT qualify as physical evidence?

Physical evidence refers to tangible objects that can be collected and analyzed to help establish facts in a case. It includes items that can be physically examined, tested, and preserved, which play a crucial role in investigations, particularly in the context of fire investigations.

Witness statements, while valuable for providing context and perspective on an incident, are not physical evidence. They are subjective accounts gathered from individuals who observed the incident and cannot be physically analyzed or tested in the same way as objects can. Therefore, witness statements rely on interpretation and are considered testimonial evidence rather than physical evidence.

In contrast, evidence from a security camera, fire debris, and blood samples are all physical in nature, allowing investigators to utilize forensic techniques to extract meaningful data that contributes to understanding the fire's cause, effects, and potential criminal activity surrounding the incident.
