Which type of evidence is NOT typically used for positive identification?

Video recordings are not typically used for positive identification in the same way that fingerprints, DNA testing, and X-rays are. Positive identification relies on comparing unique biological or physical traits of individuals against established records.

Fingerprints are highly distinctive and have been a fundamental method for personal identification in forensic science. They can link a person to a crime scene definitively due to the uniqueness of ridge patterns.

DNA testing is considered one of the most reliable forms of identification, as it analyzes genetic material that is also unique to each individual (except for identical twins). This method can provide conclusive evidence of identity in forensic investigations.

X-rays can be useful for identification, particularly in cases where skeletal remains are involved, as individual skeletal characteristics can be matched to medical or dental records for positive identification.

In contrast, while video recordings might provide visual evidence of a person's presence or actions, they typically do not confirm identity with the same level of certainty. Factors such as the quality of the footage, angles, distance, and environmental conditions can greatly affect identification through video. Therefore, it is less reliable as a standalone method for positive identification compared to the other options presented.
