`` Do Fingerprints Lie? By Michael Specter

Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011). By analyzing this junk code, Jeffreys found certain sequences of 10 to 100 base pairs repeated multiple times. These tandem

Due to the brief period that Hodge had been allowed to see her attacker, the prosecution felt that stronger evidence was needed to prove a connection. The brief 6-second glimpse that the victim Nancy Hodge obtained during her ordeal wasn’t considered viable enough for trial purposes (Lewis). This relatively new forensic investigation technic involving the use of DNA fingerprinting was in its infancy and was pioneered by a British scientist might hold the answer to convicting the rapist.

Forensic science has become the greatest collective method for intelligence gathering of human identifiers. The forensic sciences are used around the world to resolve civil disputes, to justly the enforcement of criminal laws and government regulations, and to protect public health. Over the years, judges have trusted forensic methods without a second thought. DNA analysis is the most reliable method that forensic has, but how reliable is it? (Jonathan Jones, pbs). According to a group called The Innocence Project, “Misapplication of forensic science is the second most common contributing factor to wrongful convictions, found in nearly half (46%) of DNA exoneration cases” (Innocence project).

For over a century fingerprints have been one of the most used tools of forensic science. Fingerprints have been used to identify criminals of small crimes

There are times when certain forms of evidence, such as blood and fingerprints, need to be obtained before the accused has time to destroy them (Inabau 2).

“In 1984, a British geneticist named Alec Jeffreys stumbled upon one of our most important forensic tools: DNA fingerprinting. Since his “eureka moment,” the scientific technique has been used successfully to identify perpetrators of a crime, clarify paternity and exonerate people wrongly convicted” (Jones). DNA evidence, specifically simple-mixture, is the most accurate type of forensic evidence we currently have at our disposal, but even it is not infallible. Other types of forensic evidence are much less accurate, but unfortunately their use is still permitted in U.S courtrooms. Jurors may be misled by experts within the courtroom as well. These misconceptions about the accuracy of forensic science and the field in general lead to many problems in the courtroom.

The use of fingerprinting as a means of identification was born out of the need of law enforcement officials to have permanent records that could determine if a convict had been previously arrested or imprisoned. Before the advent of fingerprinting, law enforcement used a number of different methods to try to accomplish this. Ancient civilizations would tattoo or physically maim prisoners. In more recent times, daguerreotyping (that is, photographing) was used, but proved to be less than reliable, because people had the ability to dramatically alter their appearance (Skopitz). As a result, this method too, became obsolete with the discovery of fingerprinting, an absolutely infallible

In chapter 10 of Lee Strobel’s The Case for Christ, entitled “The Fingerprint Evidence: Did Jesus – and Jesus Alone – Match the Identity of the Messiah?” the author attempts to convince his audience that there is hard evidence of Jesus Christ being the one and only Messiah. Strobel opens this chapter by creatively linking the title of the chapter to the importance of fingerprint evidence in the world of criminology. The example of the murder case that “changed criminal law in America forever” underlines the importance that the concept of fingerprint evidence has had in many situations throughout time (Strobel 253). The goal of this anecdote is to point out the different form of fingerprint evidence that can be attributed to the life of Jesus

Forensic Evidence helps eliminate the suspects of a case. This evidence serves as the weight to tip the scales of justice as proven in paragraph seven. The fingerprints in this evidence because it shows where the suspect has been and what he’s touched. This usually proves the suspect guilty or not. Forensic Science usually ends the case using

The automated Fingerprint Identification System is also known as the AFIS within the law enforcement division (FBI, 2010). This system is an important element in the criminal justice system as some of its features encompass the storing of data, encoding, and fingerprint and facial comparison through graphics and other techniques. Law officials many centuries ago in the pursuit of positively identifying someone suspected of guilt have long used fingerprints techniques. Fingerprinting is also used in branches of our government, and in the Pentagon, the authentication method of fingerprints is used permit access to specified zones inside the building. Fingerprints are an effective and very precise method of identification purposes that does not pose

“Fingerprint recognition is one of the divorce inference using the impressions made by the minute ridge formations or patterns found on the fingertips. No two people have exactly the same arrangement of the ridge patterns, and the remaining patterns of any one individual unchanged. Fingerprints infallible provide a means of personal identification. Other personal characteristics may change, but not fingerprints”. (1)

Fingerprinting is used for many things, such as a robbery, or at a crime scene. Fingerprints were first discovered in 1870 by Alphonse Bertillon, who was a French anthropologist. In 1892, Juan Vucetich had made the first criminal report using a fingerprint. In 1905 America used fingerprints for identification. When America started using fingerprints for identification they had to match the fingerprints manually when needed. When technology was able to enter fingerprints, and match them with anonymous ones, it helped identification immensely.

Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.

DNA fingerprinting is a scientific technology involving the extraction, replication and arrangement of strands of an organism’s DNA. This results in the formation of a genetically distinctive fingerprint that is unique to the organism which the DNA sample was originally extracted from. Because of the specificity of a DNA fingerprint, the application of this technology can have a substantial influence on many aspects of society. Accessibility to a DNA database allows for higher efficiency in forensic investigations, personal identification, maternal and paternal testing. The availability of a national database to police officers and forensic scientists would equate to increased productivity in investigations and prosecution of suspects in a
