In the age of new technology, collecting fingerprints on applicants for direct care providers in the healthcare system, school teachers, and day care workers is a simple procedure and . These details include ridges, loops, whorls and other points of similarities. The coming paradigm shift in forensic identification science. The training program should contain detailed information, with milestones identified for continued skills development. No two people have the same pattern of friction ridges. If the root cause can be determined, then proper corrective steps can be initiated. In latent print examination, the examiner attempts to disprove (falsify) the primary hypothesis that a latent print and a known print originated from the same source and, if successful, accepts. Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). Generally these factors can be grouped under two categories of bias: Documenting work activities represents a key component of a QA system that supports the reliability of a specific work product. Pros and Cons of Fingerprint Evidence - Blogger The quality of the information is as valuable a consideration as the quantity, and the interpretation of information located in areas of distortion must be assessed appropriately. Fingerprints - an overview | ScienceDirect Topics As a result, the chance that human errors will be made or repeated is constantly changing. Reznicek, M., Ruth, R. M., and Schilens, D. ACE-V and the scientific method. Such metrics could improve the standard for sufficiency by establishing a holistic sufficiency standard that can be applied more objectively and uniformly across the discipline. Roberts, M., Larson, A., Shay, M., and Lien, D. A comparison of fingerprint patterns between twins and the general population. ASCLD/LAB. Pankanti, S., Prabhakar, S., and Jain, A. K. On the individuality of fingerprints, IEEE Transactions on Pattern Analysis and Machine Intelligence (2002) 24(8):10101025. Better technology can improve identification accuracy. The Pros And Cons Of Fingerprinting | ipl.org Latent prints are typically collected from a crime scene by specialists trained in forensic science techniques to reveal or extract fingerprints from surfaces and objects using chemical or physical methods. We wrote this article from our perspective as FBI Laboratory latent print examiners. ASCLD/LAB, Garner, North Carolina, 2006a. SWGFAST training to competency for latent print examiners, version 2.1 [Online]. The DNA Fingerprint Act of 2005 requires that, beginning January 1, 2009, any adult arrested for a federal crime provide a DNA sample. SWGFAST membership consists of up to 50 individuals from international, federal, state, and local forensic science laboratories as well as from private practice. When a fire occurs, fire investigators are called to the scene to determine the cause of the fire and the potential for arson. The advantages of this type of program are that initial/fundamental latent print examiner training becomes more centralized and helps to ensure that all latent print examiners receive consistent and thorough training. A cross-over is a little ridge that joins two parallel ridges. It does not join neighboring ridges. But Forensic dna also has many cons too like how dna can be tampered with and can falsely incriminate innocent . The erroneous identification is the most serious error in data interpretation that an examiner can make because it may falsely associate a person with an item of evidence. This conclusion does not imply that the source did not have contact with the particular item(s), because it is possible for an individual to touch or handle an item and not leave a latent print suitable for comparison purposes. Thus, preventing buddy punching or clocking in early or clocking out late. In fact, as FRONTLINE reported in the 2010 film Death by Fire, many of the supposed telltale signs of arson the remnants of accelerant pour patterns, for example can actually be caused by natural phenomena during accidental fires. Fingerprint databases typically contain rolled fingerprints from each finger ("tenprints") and fingerprints from the whole hand with all the fingers extended in parallel ("slaps"). Lin, C. H., Liu, J. H., Osterburg, J. W., and Nicol, J. D. Fingerprint comparison. Hale, A. R. Morphogenesis of volar skin in the human fetus, The American Journal of Anatomy (1952) 91:147181. To appreciate how qualified forensic examiners apply the holistic standard, it is necessary to understand how examiners develop individual thresholds and how the laboratory system establishes the uniformity of these thresholds. SWGFAST has set forth guidelines for the minimum qualifications for latent print examiner trainees (SWGFAST 2002b). More accurate time keeping. All evidence transfers should be captured on a chain-of-custody report. Corrective actions should not be viewed as punitive but as a chance to detect, correct, and improve on any situations or conditions that are affecting the quality and integrity of the work product. (Manuscript in preparation). In the latent print discipline, it is not yet known how to establish a direct correlation between error history and prediction of future errors or if it is even scientifically possible to do so. You'll receive access to exclusive information and early alerts about our documentaries and investigations. From these he estimates that false matches occurred at a rate of 0.8 per cent . When comparing friction ridge impressions, examiners select a starting point from the latent print at their discretion. A report on the erroneous fingerprint individualization in the Madrid train bombing case, http://www.fbi.gov/hq/lab/fsc/backissu/jan2005/special_report/2005_special_report.htm. These potentially biasing factors exist in every scientific endeavor. Latent fingerprints used in criminal investigations are often crucial pieces of evidence that can link a suspect to a crime. For example, an examiner may determine that two prints originated from the same source based upon all of the information present in the two prints but that the quantity of a specific subset of this information does not fulfill that examiners mandated numerical standard. It was determined that sole reliance on ridge characteristicsdefined as ending ridges, bifurcations, and dotsignored a wealth of additional information considered during the analysis and comparison of latent prints. Investigators and prosecuting attorneys alike greatly value fingerprint evidence and its ability to sway judges and juries toward a conviction. This may lead to a larger number of unworked cases initially, but would eventually increase the number of cases worked in the future by providing additional qualified examiners. If a good print is found at a crime scene it may be photographed (well) and/or lifted in order to compare through the national database. The ACE-V (Analysis, Comparison, Evaluation, and Verification) methodology. 1.2.1 There is no scientific basis for requiring that a predetermined number of corresponding friction ridge details be present in two impressions in order to effect individualization. External audits typically focus on the same areas of concern as the internal audits. Mayfield later sued the government, which settled for $2 million. Over time, additional documentation requirements have developed from necessity, and others have derived from legislative mandate. Increasing the number of funded latent print examiner positions available, in combination with standardized training, would greatly improve turnaround times of cases in laboratories across the country, as well as provide consistent and accurate results in a timely manner. Using DNA evidence in court has its pros and cons. The ridge flow provides the means to quickly orient and correlate the comparable area to the known exemplar. 2008). 1. Fingerprint Scanners 101: Capacitive vs. Optical vs. Ultrasonic Are Fingerprints At The Crime Scene Enough Evidence? Encourage continuing research into the factors (e.g., pressure, amount of substance being transferred, etc.) Srihari, S., Srinivasan, H., and Fang, G. Discriminability of fingerprints of twins, Journal of Forensic Identification (2008) 58:109127. These recommendations should be implemented with an added focus on establishing greater communication and uniformity in both training and practices across the latent print community. After the investigation into the cause of and failure to internally detect the Madrid error, the FBI Laboratorys Latent Print Unit (LPU) implemented improvements to its quality assurance program to help detect errors and to reduce the chance of committing such errors again. A competent examiner is trained to recognize the difference between distortion within the impression and a true discrepancy and will be able to explain this distinction in court (SWGFAST 2002c). Forensic Tools: What's Reliable and What's Not-So-Scientific - PBS Champod, C., Lennard, C., and Margot, P. Alphonse Bertillon and dactyloscopy, Journal of Forensic Identification (1993) 43:604625. Support the development of a comprehensive statistical model that more accurately incorporates the information taken into account by the latent print examiner. Before beginning casework, all examiners should be competent to perform the required procedures. A .gov website belongs to an official government organization in the United States. It happens when a defendant testifies to questioning. SWGFAST quality assurance guidelines for latent print examiners, version 3.0 [Online]. Integral to the standards for conclusions is the concept of sufficiency, or how much information is needed to support the statement of identification of a single source (SWGFAST 2002a). This experiential approach enables trainees to learn the threshold other qualified examiners apply, thereby maintaining a consensus threshold within a laboratory system. To increase the number of qualified latent print examiners and maintain the consistency and accuracy of latent print examinations, the latent print community needs to determine the minimum qualifications necessary for latent print examiner trainees, establish a standard training curriculum and certification program that can be implemented nationally, and require annual proficiency testing of certified latent print examiners. A report of latent print examiner accuracy during comparison training exercises, Journal of Forensic Identification (2006) 56:5593. Funding for FRONTLINE is provided through the support of PBS viewers and by the Corporation for Public Broadcasting. The pros and cons of biometric authentication | TechTarget Abstract. The verification phase includes independent analysis, comparison, and evaluation documented on a separate photograph(s). Barton Associates: Digital vs. Traditional Ink Fingerprinting If the laboratory meets the required needs, the review also establishes whether case reports contain accurate information to allow for the interpretation of the results. The accused knows the nature of the charges and the evidence supporting the charges. Figure 2F highlights the individuality created by the aggregate of the friction ridges and their features. Institute latent print examiner training as part of a college or university degree program. Record and/or present the conclusions. All individualizations are subject to verification. Babler, W. J. Prenatal development of dermatoglyphic digital patterns: Associations with epidermal ridge, volar pad and bone morphology, Collegium Antropologicum (1987) 11:297303. Such a record allows for the review of activities if the quality of a specific work product comes into question or if an error is detected. Latent prints are undetectable to the naked eye. Over the years, higher demand for scientific and analytical capabilities for the fingerprint discipline has prompted the FBI and some other laboratories to increase the minimum qualifications to require at least a bachelors degree, whereas other laboratories require a bachelor of science degree, with a masters degree preferred. Although not strictly a part of the scientific basis for latent print examination, a quality assurance (QA) program remains essential for producing a reliable work product. List of Cons of DNA Fingerprinting 1. At this point in friction ridge examination, testing begins. The uniformity of examiner thresholds is established through training by empirical study, consultation, and verification with experienced, qualified trainers. In an investigation, a court may notice an error interfering with the defendants rights. Given its early use, it is not surprising that the latent print discipline developed a period of relatively unquestioned acceptance. As illustrated by the lines that connect the features in the middle of the impression, the ridge flow, the ridges in sequence, and the ridge characteristics in sequence together provide the basis for sufficiency. (Photo: Isabelle Armand) In May 1992, Noxubee County, Mississippi, was rocked by the discovery of the body of three-year-old Christine Jackson in a creek about 500 yards . As new fingerprints are added to the AFIS, criminal investigators can search them against the ULF collection in the hope of making a match. Attorneys for the Innocence Project say that the scarcity of research backing up bite mark comparisons played a role in a number of wrongful convictions over the years. Figure 2C highlights the overall flow of the friction ridges. Maltoni, D., Maio, D., Jain, A. K., and Prabhakar, S. Fingerprint individuality. Everyone has a unique set of prints. . There have been a number of people who were convicted based on bite-mark testimony who were sent to death row or sent to prison for life, says Neufeld, who represented both Levon Brooks and Kennedy Brewer, both wrongly convicted based in large part on faulty bite mark testimony. Figure 1: Three friction ridge impressions: (A) a small, distorted impression; (B) one of slightly better quality; (C) a clear impression. However, in the determination of sufficiency, even these characteristics are not merely counted, but rather their value is based on the type, position, direction, and spatial relationship of each characteristic within the aggregate of all information. Babler, W. J. Prenatal development of dermatoglyphic digital patterns: Associations with epidermal ridge, volar pad and bone morphology. The admissibility of fingerprint evidence: An African perspective Watch this excerpt from Death by Fire for more on the emergence of new fire science and how it called into question the guilt of Cameron Todd Willingham, who was executed in 2004 after being found guilty of the arson-murder of his three young children: Also known as forensic toxicology, the analysis of controlled substances involves the collection of chemicals that have the legally recognized potential for abuse. The court may allow the request if the evidence breaches the defendants rights. Figure 2A highlights the size and shape of the latent friction ridge impression. A dot is a ridge in the center of other ridges but does not connect. Extinguishing a fire and investigating a fire involve two different skill sets and two different mindsets., Another scientific expert, Gerald Hurst, offered a startling devils advocate opinion about the state of arson testimony in the courtroom: I could take almost any fire and if I were so inclined convince a jury that it was arson. The defendant provides grounds for removing evidence. Have latent examiners at all levels of government attend a training program at a federal laboratory. The SWGFAST standard for individualization follows. (January 2005). After becoming certified, examiners would be required to take an annual proficiency examination to maintain their status as certified latent print examiners. Figure 5 depicts an exclusion scenario. Latent Print Operations Manual: Standard Operating Procedures for Examining Friction Ridge Prints. Ashbaugh, D. R. The premises of friction ridge identification, clarity, and the identification process, Guest Editorial, Journal of Forensic Identification (1994) 44:499516. Section 5.10.3.5. The guideline states that successful students must demonstrate knowledge of required objectives by passing written tests and/or practical exercises and by communicating an understanding of the objectives and underlying principles. In fingerprints one can often observe similar features like whorls, loops, etc, occurring in the same finger of two individuals. It is a general process that can be followed in any endeavor involving the comparison of two (or more) objects. Forces Left Afghanistan. Dror, I. E., Charlton, D., and Pron, A. E. Contextual information renders experts vulnerable to making erroneous identifications, Preliminary Communication, Forensic Science International (2006) 156:7478. Securing a just verdict: Evidence is important in securing a fair case outcome. Saks, M. J. and Koehler, J. J. To achieve source attribution, both the friction ridge impression and known exemplar must have sufficient quality and quantity of information. Create an argument that discusses the pros and cons of using fingerprints as evidence for convicting a person of a crime. Because the human brain is capable of analyzing and comparing more information than can be effectively illustrated here, these figures are not intended to represent all of the information examiners consider during the comparison process. The prints leave impressions on the surfaces we touch. The prosecutor fails to offer evidence to challenge its credibility. This documentation should include a unique identifier for each item, a chain-of-custody report with each item documented, and a record of the surfaces from which any lifts or photographs were taken. If the examiner determines that the information is of sufficient quality and quantity, the print is declared of value for individualization. Explore Till's life, murder and legacy through the 'Un(re)solved' project. There are many pros to forensic dna like solving crimes and finding criminals. A ridge begins as a single line before spreading out and reconnecting as a continuous line. A latent print examiner may have as few as two weeks or as many as two years of training (the FBI Laboratory prefers the latter). THE PROS AND CONS OF FINGERPRINTING: Background Checks - ResearchGate This argument demonstrates a certain navet regarding the disparate nature of the information considered in the various forensic disciplines. For years, forensic hair examiners have testified that physical characteristics of hairs can be identified and used to establish the presence, or absence, of certain people at a crime scene. To compound this situation, a shortage of qualified latent print examiners exists because of a lack of funding to staff these positions and a lack of consistency in the education, training, and skill level of latent print examiners. You can raise reasonable doubt. Although the guideline provides a good foundation for the knowledge desired for competent latent print examiners, it does not address the structure of a qualified training program. The scientific method is a formula used to reduce subjectivity in any scientific endeavor. The following paragraphs outline elements of the current QA program employed in the Latent Print Unit of the FBI Laboratory, an ASCLD/LAB-accredited laboratory. Inconclusive decisions should be annotated on the photograph by the notation inconclusive or inc, in addition to the name of the individual and identifying information, if known and when appropriate. It sets the president for a working legal system. It is hard to judge character objectively. SWGFAST recommends that individuals possess, at a minimum, a bachelors degree from an accredited college or university. DNA Evidence in Court: Pros and Cons | The Shocking Truth - Carl Stoney, D. A. and Thornton, J. I. Part Three of FRONTLINEs documentary series America and the Taliban examines the United States rushed exit from Afghanistan and what it left behind. These areas of uncertainty are represented by the gaps in the outlined paths. Other examiners may have experienced difficult analyses, examinations, or unusual circumstances and may have knowledge that will assist in the examination. As with any other scientific endeavor that involves human beings, latent print examination is not infallible. Standardization Committee report. 1. These features provide the examiner with an effective and efficient means to reach an exclusion. With such a difference in the amount of training received, the skill level of latent print examiners varies immensely. What Are the Pros & Cons of Fingerprint Recognition Technology? They are more secure than capacitive scanners and, of course, definitely more reliable than optical scanners. Certain limits apply to the jury during the first questioning. These are the results of proficiency tests cited by Cole in the Journal of Criminal Law & Criminology (vol 93, p 985). The results of these studies provided the initial support for the tenet that friction ridge skin could be used to individualize. Birth Defects: Original Article Series. Historically, documentation in the latent print discipline had been minimal when compared to other scientific endeavors. The documented result should include the presence or absence of any prints and the indication of whether the developed prints are suitable for capture either through scanning or photography. SWGFAST has established specific standards for these three conclusions that have achieved general acceptance within the latent print community. SWGFAST friction ridge examination methodology for latent print examiners, version 1.01 [Online]. It is used to make inferences on an individuals death, illness, and mental or physical impairment. After completing the activities in this unit, you will develop an argumentative response to the question: Should fingerprints be the only piece of evidence used to convict a person of a crime? The defendant requests a jury not to be present because they are a witness. Milner & Company, Halifax, England, 1912. Pros. The SWGFAST standard for inconclusive follows. The question of sufficiency continues throughout the comparison process and, in particular, when the corresponding area of a latent print is not fully recorded in the known. If not cautious (or vigilant), an examiner may be influenced by the knowledge of specific case information (Ashbaugh 1991; Dror and Charlton 2006; Dror et al. A Comprehensive Guide To Bond Conditions, How To Get Around Cash-Only Bond: A Guide For Those In Need Of Legal Help, Does A Verbal Agreement Hold Up In Court? Perspective on errors, bias, and interpretation in the forensic sciences and direction for continuing advancement, Journal of Forensic Sciences (2009) 54:798809. Testimony can be evaluated by any court official or reviewed for technical accuracy by a subject-matter expert who either directly observes the testimony or reviews a transcript. As of May 2009, SWGFAST has published the following documents (see http://www.swgfast.org): Through these documents, SWGFAST intends to guide the community so that competently trained examiners can perform quality forensic examinations by adhering to standard operating procedures linked to a strong and committed quality assurance program. This in turn produces accurate and reliable conclusions. Case documentation is not complete if the record-keeping process does not begin at the crime scene. Dror, I. E., Pron, A. E., Hind, S.-L., and Charlton, D. When emotions get the better of us: The effect of contextual top-down processing on matching fingerprints. The views expressed in this article are those of the authors and do not necessarily reflect the official policy or position of the FBI or the U.S. Government. Review Article - Latent Prints: A Perspective on the State of the It is the responsibility of the friction ridge community, working in concert with the legal community, to determine how to most effectively relate the basis, standards, significance, and limitations of latent print examiner conclusions. Ashbaugh, D. R. Quantitative-Qualitative Friction Ridge Analysis: An Introduction to Basic and Advanced Ridgeology. A jury gets excluded if: During the first questioning, a defendant may remove themselves from future cross-examination. Huber, R. A. Among the biggest problems that we uncovered in the report is the absence of the application of scientific methodology to determine whether or not the discipline was valid and reliable as was done with DNA, says Harry T. Edwards, a U.S. federal judge and part of the NAS committee that produced that 2009 report. Pros and Cons of DNA Evidence | The Ambeau Law Firm When performing examinations, latent print examiners follow a four-step process: Analysis, Comparison, Evaluation, and Verification (ACE-V). For this reason, in the past, the methodological error rate has been somewhat confusingly stated as zero (Cole 2005; Wertheim et al. It saves the courts time as the prosecution has to narrow it down to acceptable proof. Examples of internal audits include case file, court testimony, training records, continuing education, proficiency testing, security, control of standards and reagents, instrument calibration, document control, and evidence security.
