Forensic evidence refers to evidence that is collected and analyzed using scientific methods to support legal investigations and proceedings. This definition encompasses a variety of materials and data that can be utilized in a court of law, reflecting a systematic approach to gathering information that is often crucial for solving crimes.

The scientific methods employed in forensic analysis can include chemical testing, DNA profiling, ballistics, and more, ensuring that the evidence is reliable and can be reproduced under similar conditions. This rigorous procedural framework helps to establish the validity of the findings and their admissibility in court.

In contrast, evidence from public records is typically not subject to the same rigorous scientific scrutiny that forensic evidence undergoes. Physical evidence from a crime scene is part of what might be analyzed scientifically, but not all physical evidence qualifies as forensic unless it is collected and studied using these methods. Witness testimonies, while important, rely on human recollection and are not scientifically analyzed in the same way as forensic evidence, which can lead to variances in reliability and accuracy.
