The Importance Of Fingerprints In The Criminal Justice System

The leader of the gang's name was Ralph Fleagle, and he was accompanied by his brother and two other friends. They were caught by fingerprint which was the first time the FBI used a single fingerprint to ever solve a crime. When they were caught, most sentenced to hang and died in a two week period in July 1930, but Jake Fleagle was killed in a shootout (The Fleagle Gang).

Hayes did not give consent to be taken to the police station and be detained plus fingerprint. Therefore, Hayed Fourth Amendment rights were violated and the conviction was overturned.

Fingerprints are a significant form of forensic evidence because they define an individual. Every time people touch something, “they leave a little bit of themselves behind” (Sohn
Fingerprint analysis is a method of identifying individuals based on the unique patterns of ridges and valleys on their fingertips. In Dahmer's case, investigators were able to use fingerprints to identify the remains of his victims and link them to specific crime scenes. Fingerprint analysis has been used in forensic investigations for over a century and is considered to be a highly reliable method of identification. It is based on the fact that no two individuals have the same fingerprint patterns and that these patterns remain consistent throughout a person's life. In Dahmer's case, fingerprint analysis was used to identify the remains of several of his victims, including Anthony Sears and Ernest Miller.
Fingerprint is standard procedure when getting arrested or getting any sort of government jobs
The Richard Ramirez "Night Stalker" case was one of the first major cases to use automated fingerprinting technology (Frese, 2011). Today, the fingerprinting database gives various probable identifications, then a trained fingerprint expert must compare the prints to find a likely identification. Considering that Ramirez's prints were found on the mirror of a stolen vehicle we can conclude that his fingerprints were two-dimensional, therefore the prints are termed as latent or residue prints. The authorities at the crime scene power-dusted his prints considering that is the best physical method for collecting fingerprints. Once analyzed using the ACE-V (analysis, comparison, evaluation and verification) method, the fingerprint expert was able to identify them as belonging to Ramirez.
My thoughts Forensic science is used everywhere. It can be used to arrest and convict someone of a crime. Before watching The Real CSI video, I thought using fingerprints and DNA will get you 100% accurate results. Throughout the video my thoughts about the subject began to change.
Today, practical methods of using fingerprinting are extremely wide. In 1995, the size of the FBI fingerprint card archive contained over 200 million items, and archive size was increasing at the rate of 30,000 to 50,000 new cards per day [2]. Forensic science was the very first and most important area of its application, which still remains. The rapid development of computer technology has made it possible to create such fingerprint scanners that can be installed on laptops, cell phones, flash drives,
In the lab report three students are tested along with one suspect. Student number two’s DNA matched the suspects DNA. The student’s DNA’s are cut with five different enzymes as well as the suspects DNA. Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.
One case that relates to this flaw in the criminal justice system would be the Floyd v. City of New York. The date that this case was filed was on January 31, 2008 by David Floyd, David Ourlicht, Lalit Clarkson and Deon Dennis. This case challenged the New York Police Department’s (NYPD) practices of racial profiling and seeing whether or not the stop and frisk policy is unconstitutional. The clients represents thousands of black and Hispanic New Yorkers who have been stopped for no reason (according to the clients).
Crime Myths Most crimes are solved by fingerprints and DNA. This is a prime example of a crime myth. The truth is less than 1 percent of all serious crimes are solved by DNA, and fingerprints do only slightly better. As mentioned in USA Today titled "Crime and the media: Myths and reality", it discusses some of the important insight to crime in the media causing myths. Another source that covers this topic is in an Irish Times article by O’ Toole, Fintan entitled “Myths that conceal the truth about roots of crime: [CITY EDITION]” it goes over the many aspects that relate to myths that are contributing to the truth about roots of crime.

Varied policies Policies among local agencies varies greatly.
DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
