Why is physical evidence considered crucial in investigations?

2. It can be easily altered

3. It is subjective

4. It requires no analysis to be understood

The correct answer is: It is more reliable than witness testimony

Physical evidence is considered crucial in investigations primarily because it is more reliable than witness testimony. Witnesses may have biases, may misremember details, or may be influenced by external factors, which can lead to inconsistencies in their accounts. In contrast, physical evidence, such as fingerprints, blood samples, or other tangible items collected from a crime scene, remains constant and can be scientifically examined and verified. This reliability allows investigators to reconstruct events accurately and provide concrete support for their conclusions. When physical evidence is properly collected, preserved, and analyzed, it can offer objective facts that bolster a case, making it a cornerstone of effective investigation practices. Such evidence can provide definitive links between a victim, a suspect, and a crime scene, ultimately facilitating the pursuit of justice.
