Forensic Science Gone Wrong


Forensic science is any science that is used for legal purposes. While forensic evidence can be used in civil cases, it is most often associated with criminal cases. Both the defendant and the prosecutor can use the unbiased information found through forensic science to support their case. However, forensic science can sometimes be flawed. When this incorrect information is digested by a jury, innocent people get sent to prison. It is important to work with a defense counsel that has a strong grasp on what is and is not acceptable forms of forensic evidence, and is able to make arguments, when necessary, as to why a certain expert witness’s opinion or piece of evidence should not be held up as fact in the mind of the court.

Types of Forensic Science Used in Court

The American Academy of Forensic Scientists separates the field into several disciplines:

  • Anthropology – used to excavate and examine human remains;
  • Criminalistics – examines evidence such as fingerprints, fabric threads, or bullet holes;
  • Digital and Multimedia Sciences – reviews media such as photography or cell phone records;
  • Engineering Sciences – Anywhere an engineering background would help understand a case;
  • Jurisprudence – often also a lawyer, this person is able to clearly present evidence in court;
  • General – used for any category not fully developed yet;
  • Odontology – dental knowledge that might help identify a person, examine bite marks, etc.;
  • Pathology – completes an autopsy and helps identify cause of death;
  • Psychiatry and Behavioral Sciences – determines if a person is fit to stand trial or mentally ill;
  • Toxicology – examines the possible impacts of drugs or chemicals in a case; and
  • Questioned Document Examination – examines documents for forgery, alterations, etc..

All of these sub-fields use some hard sciences to come to conclusions in a case, however, the results aren’t always objective. BBC News highlighted a case where hair analysis put an innocent man in jail for 28 years. Hair follicles found on victims that looked as though they matched the suspect were used as evidence throughout the 1980’s and 1990’s. However, it is easy for two people to disagree on whether or not hair follicles look like a match.

Forensic Science is Also Used to Free Wrongly Convicted People

In Virginia, a man was recently released from Nottoway Correctional Center after DNA evidence determined he was innocent. The New York Times reported that the man was originally convicted based on evidence that claimed the bite marks on the victim were caused by him. Even DNA, which has become a golden standard for forensic science, can be disputed amongst experts.

Call an Attorney at Once 

It is important to point out that expert testimonies are important to court cases. Moreover, forensic science is not biased towards a particular side in the courtroom. At times it just isn’t enough to prove a suspect is innocent or guilty. This is why it is crucial to have an experienced criminal attorney to guide you through any criminal charges and subsequent legal proceedings.
