What is Forensics/Crime?
Forensics is basically finding evidence to solve a crime. It could also mean that it has to do with the courts or legal system. When a crime is committed, police and forensic scientists collect and analyze physical evidence. Most technicians specialize in either crime scene investigation or laboratory analysis. This involves fingerprints, blood, firearms, saliva, and drugs, and may also have to build skeletal bones. In addition, forensic scientists write reports, preserve evidence, and testify in court with a law enforcement personal. Often times, the scientific breakdown of evidence is important in determining an accused person’s guilt or innocence in a crime.
CSI
Crmie scene investigators (CSIs) are called evidence technician, crime scene technician, forensic investigator, crime scene analyst, and more. CSIs spend most of their time in the field, working at crime scenes. The CSI’s job is to: secure the crime, scene,take detailed measurements sketch and diagram the scene, document evidence taken from the scene (anywhere basically), package and label evidence for transfer to the lab, and testify to their findings in court. The physical evidence collected by CSIs may include fingerprints, footprints, trace materials, hair and fibers and biological evidence found at the scene and on the victim’s body. The evidence collected by the CSI is then transferred to a lab, with many evidence procedures. In the lab, technicians, including forensic chemists, forensic biologists and forensic toxicologists, analyze the samples.Forensic science is used to help identify victims of crimes and victims of disasters. and war zones. Using the polymerase chain reaction process can make millions of copies of DNA from just a few skin cells. These DNA techniques can help tie criminals to a crime and victim. DNA is also used in disaster situations where bodies may not be able to be identified by other means. This allows the remains to go back to the rightful families and gives those families closure.
The Negative Side
The modern age of forensic science, it seems like there’s no way for a murderer to escape punishment if there’s forensic data, and there’s no way that data can be wrong. However, three of the most common methods of convicting a person fingerprinting, DNA and bullet ballistics aren’t 100-percent accurate. The equipment used in forensics is expensive. It requires precise and accurate analysis. Even if a minor error occurs in the analysis, it may result in the wrong figure. The evidence cannot be accessible at all times. Interpretation of the analysis different from one forensic scientist to another so it causes confusion. Forensic analysis can be prevented by strong influences (political or financial factors). Also ,maintaining privacy and secrecy of the information gathered through forensic analysis is quite difficult.
The Positive Side
The use of DNA evidence has resulted in overturning the sentences of 250 jury-convicted individuals in the United States, (according the to Justice Project). The use of forensic science, specifically DNA testing, has helped earn many of these individuals freedom. Forensic science is used to help identify victims of crimes and victims of disasters. Using the polymerase chain reaction (PCR) process can make millions of copies of DNA from just a few skin cells. These DNA techniques can help tie criminals to a crime and victim. DNA is also used in disaster situations where bodies may not be able to be identified by other means. This allows the remains to go back to the rightful families and gives those families closure.
