Which of the following is considered a type of physical evidence?

Physical evidence refers to tangible objects that can be collected and analyzed to support or refute a hypothesis about a crime. Fingerprints serve as a prime example of physical evidence because they are unique to an individual and can be used for identification purposes. When fingerprints are collected at a crime scene, they can be analyzed and matched to individuals, thereby serving as concrete evidence in an investigation.

Witness statements and police reports, while valuable for providing context and insights into the events surrounding a crime, are not classified as physical evidence because they do not involve objects or materials from the crime scene. Video footage, although it captures physical scenarios, is often considered a form of documentary or electronic evidence rather than physical evidence, as it doesn't include tangible items. Fingerprints, on the other hand, are a direct form of physical evidence that can be directly linked to an individual, making them particularly significant in forensic analysis.
