rui-silvestre-703796-unsplash-copy-242x300Our criminal justice system was founded on the idea that it is better to let a man go free than to imprison him unjustly. For that reason, prosecutors are held to a very high standard of proof. In many cases, this proof is acquired using scientific means. However, sometimes these means are not so scientific and other times the methods of quality control are severely flawed.

In 2016, Judged Stuart Katz dismissed a complaint against a Chicago juvenile when fingerprint evidence was brought against him. The forensic officer involved in matching the prints was castigated in court after the Judge found a number of methodological flaws in the man’s work. The judge accused the Sergeant of being “oblivious” and “not caring about educating himself” in his own field or work. He went onto say that there appeared to be no audits or any method of verification and that they did not follow the basic procedures set forth by the FBI. The judge determined that the entire department needed to clean up its act or they would find it very difficult to enter forensic evidence into the record during future trials.

The FBI is Just as Bad

tertia-van-rensburg-37121-copy-300x224Juries in Illinois and other states have been asked to measure the reliability of latent fingerprint evidence for decades. Latent fingerprints are collected samples of hidden fingerprints in a crime scene. Examiners use them to relate with those that are known to come from recognized sources. Forensic science is crucial in examining crime and assisting in the verdict for innocence or guilt at court hearings.

Questions concerning the sufficiency of several forensic subjects are arising daily. In 2009, a report was issued by the National Research Council that claimed that most latent fingerprint analyses were scientifically unjustified. It also said that some forensic disciplines had no credibility at all.

However, many reports still regard it as scientific injustice. In 2016, a group working on latent fingerprint analysis concluded that the forensics were not justified. The groups say that such assertions have brought false convictions and arrests. The American Association for the Advancement of Science made conclusions in a report. They said latent fingerprint examiners should stop claiming concealed fingerprints come from one source. Furthermore, they should particularly stop saying they could prove as much without errors.
