Understanding Forensic Testimony: The What and Why

Forensic testimony is a type of evidence presented during a legal proceeding. It is given by experts who have studied, evaluated, and analyzed physical evidence, and then given an opinion based on their findings. This type of evidence may be used to tie a suspect to a crime scene, or to prove the reliability of a drug test, or to prove that certain evidence was manipulated. Forensic testimony can be a powerful tool for lawyers to use when presenting a case.

Forensic experts may draw from a host of scientific disciplines to prepare and give their expert testimony. Common areas include but are not limited to genetics, DNA, fingerprint identification, ballistics, handwriting analysis, and toxicology. In some cases, a forensic pathologist or other medical professionals may be called upon to provide medical examinations and opinions.

Why Forensic Testimony Matters

Forensic testimony can be incredibly valuable, as it allows a jury to better understand complex evidence, such as DNA or physical evidence collected from a scene. In some cases, it can be the difference between a guilty verdict or an acquittal, or it may be used to plead for a reduced sentence, depending on the severity of the crime. For example, a lawyer representing an individual accused of a violent crime may use forensic evidence to establish claims of a defendant’s mental incapacity.
