Fingerprinting
Forensic science solves many hard crimes as they use these methods which today I will talk about fingerprinting one of the most famous methods.
Many people will agree this world will have no humanity if there is no forensic scientists without it criminals will not be convicted of their crimes people will go crazy and do homicidal rampage, murders will keep killing people, thieves will be more as more

houses stores banks will be stolen and drug trafficking would continue dealing. The world will be in danger nobody will live safe so you have to be thankful that we have forensic science Now fingerprinting for me one of the best methods is fingerprinting it has evolved a great deal. Long time ago prints were taken with ink and placed on paper since that moment the world changed as more technology happened now the internet and computers allow the police to place prints in a database by the FBI. The technology advances has a big effect on identifying prints in crime scenes. As I said before fingerprints has some downsides like everything nothing is perfect in this world but these small little mistakes of fingerprints can cause controversy can cause innocent people to be jailed.
Although fingerprinting is highly advanced processes there are small things it can’t do like dogs for example a finger print can’t know if the animal is a carries of a very dangerous disease called allele. Someone can wear gloves or erase the fingerprints and one of the main problems of it is that sometimes the juror finds the evidence almost invisible causing problems to solve a case. I know it sounds like its bad but remember not everything is perfect and fingerprint has good benefits the most important once is that there is very strong similarities between the fingerprints of the parents and their son you think that for example if the son did the crime and the forensic scientists identifies the finger print they might do a mistake and jail the father but no don’t think that they can identify the child’s genetic fingerprint as its made up of half the father genetic and the other half the mother so it makes It possible to identify the paternity and maternity tests. So see the fingerprint method is very useful at first it started as an ink now they use computes look how much the world has changed. There are many other methods too if you want to see how they know about the crime what they do fingerprints hair and etc. there is a series called detective Conan for me it’s one of the best detective series and its very funny and plus they put what they do how they identify the crime

Thesis Statement: In this speech I am going to explain how forensic teams use fingerprints to identify individuals.
Another discrepancy between actual forensics and how it is portrayed in the media is the availability of information in databases. There is only a small percentage of the entire population’s fingerprints or DNA samples stored within databases such as the Integrated Automated Fingerprint Identification System (IAFIS). This makes finding a match between a DNA sample or fingerprint difficult, as a match would only be found if the person’s information was already stored within the database. If there is no match previously stored in a database, the fingerprint or DNA sample could be potentially rendered useless within a trial. Typically, in order to perform an analysis, investigators must already have a suspect in mind and request a DNA or fingerprint sample from him or her. If the suspect does not want to provide one however, the sample collected as evidence may not count as valid. The CSI effect creates an idealized image that all crimes can be solved with a hair or drop of blood, but this is not always the case in real life.
Therefore, the criminal justice system relies on other nonscientific means that are not accepted or clear. Many of forensic methods have implemented in research when looking for evidence, but the methods that are not scientific and have little or anything to do with science. The result of false evidence by other means leads to false testimony by a forensic analyst. Another issue with forensic errors is that it is a challenge to find a defense expert (Giannelli, 2011). Defense experts are required to help the defense attorneys defend and breakdown all of the doubts in the prosecutors scientific findings in criminal cases. Scientific information is integral in a criminal prosecution, and a defense attorney needs to have an expert to assist he/she in discrediting the prosecution (Giannelli,
...igators a lot about a perpetrator it can not tell them his name, where he lives or if he has a previous criminal record. While DNA profiling is not the only forensic tool available, DNA testing technology and improved databases are inspiring investigators and law enforcement agencies to re-open cases that were previously considered unsolvable.
The three different main types of fingerprints are Loops, Arches, and Whorls (Jackson 1). Henry Faulds is known as the Father of Fingerprints and developing fingerprints (Jackson 1). His discovery of fingerprints has made a huge impact not only in his time but, in Modern Crime Scene Investigation (Jackson 1). Without fingerprinting, it would be very difficult to convict criminals of crimes and very hard to try to process information. Crime Scene Investigators make a huge impact in Forensic Science. We need CSI workers, without them people could only imagine what crime would be like not only in our community, but in our
The combination of forensic science and investigative work is imperative and helps ensure criminals are held accountable for the crimes they commit (FBI,
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Whereas the real picture of forensic evidence is unlike what is represented in movies and television shows where a fingerprint or a trace of hair is found, then it’s game over for the criminal. Reality is not as straightforward. As more people are exposed to the unreal forensic world through television and media the likeliness for a wrong conviction increases with juries assuming the evidence involves more science than what it really does, this is known as the CSI Effect. Further education and training is needed for the people of the court, the forensic specialists, and so called experts. The people in courts do not question any of the ‘professionals’ and just trust in their expertise. The court could overcome this perception by requiring explanation of error rates in a forensic field. To do this, testing examiner error rates will be necessary which means further research. Forensic science has such a large effect on the prosecution of suspects, experts have been known to provide questionable and at times incorrect evidence. When a false conviction occurs the true perpetrator is set free. Once realized, the public doubts the justice system and the reliability of the forensic evidence even more. At this point in time, forensic is an inexact
Crime investigators have the job to solve crime and find the suspect responsible. Sometimes the offense is very difficult to solve, but with the right pieces of evidence and tools, the investigation can be answered a little more easily. The use of fingerprints is a main tool used at crime scenes. Investigators find these at the actual crime scene and analyze them at the lab to determine whom the prints belong to. Each person has an individual print which is why this is a very useful piece of evidence. Sir Francis Galton found that the prints could be categorized into different types as well as different groups. The research of fingerprints from decades before has shaped the way detectives identify suspects and victims.
In order to pursue my dream as a Forensic Psychologists I am aware that I have to put in a lot of effort and determination in to school. There are various aspects to pursuing my career such as getting good grades, volunteering in police departments, networking, and doing an immense amount of research on my field. The career I chose requires a lot of my time not only as a student but as an adult. What I mean by this is that from now on, my time is devoted in to acquiring skills and changing my persona in order to be better qualified for the my job. Throughout this road map I will talk about what is a Forensic Psychologist, what are the requirements, skills necessary, what I could do with this degree, the personality types that are best suited for this job, and what are the prospects of moving up.
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
According to the American academy of forensic science, the forensic sciences form a vital part if the entire justice and regulatory system. Forensic science is an enticing career having to do with science and criminal justice, a large variety of schooling is needed to start this job Despite the fact that it can be a dangerous environment it can be an exciting profession to pursue. There are many different fields in forensic science that you can study or major in but they all have the same objectives.
“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
A smaller downside to crime scene investigation is the amount of time it can take to process a piece of evidence. If a crime occurs in a small town that does not have their own lab, they need to send all of their evidence to the state lab, or the next closest lab to their town. This process can take weeks, or even months, because there will be a countless number of other pieces of evidence that were brought in to be analyzed. Analyzing a blood sample or a fingerprint is paramount to a case, in that they contain DNA or personal information that can reveal who the victim or the suspect is. The longer a case takes to solve, the less of a chance there is to catch the suspect, so there has to be an alternative to speed up the process of sending evidence to state
Crime today seems as if it keeps getting worse and worse, but without forensic science would we have been able to figure out some of the main details in some cases? Forensic science is any science used to help solve a case/mystery, which is very vital when it comes to criminal investigation research. While researching my project I discovered all the many tasks and difficulties that come with forensics.
