Forensic science is one most important discipline of knowledge and skill that is key to decide any criminal and civil investigation and judicial process. understanding of Forensic science surely enhances the scope of lawyer and judge in his routine duties. Lloyd Law College with the aim of expanding the horizons of our students in legal practice and profession introduces a Practical Course in Forensic Science in campus.
Forensic science is defined as the application of science in answering questions that are of legal interest. More specifically, forensic scientists employ techniques and tools to interpret crime scene evidence and use that information in investigations. Forensic scientists and technicians come from a variety of academic backgrounds, although most have completed coursework in the life sciences, chemistry and law enforcement.
Scope of Forensic Science:
Forensic science has shaped the world of justice, fuelling crime investigations and signifying the progress of modern technology.
- Preparation for Arguments on charge (Interpretation of M.L.C, Postmortem reports & other forensic reports help the Lawyer to argue on charge)
- Preparation for the cross-examination of the witnesses (Forensic Experts, Medical Experts, Doctors etc.)
- To understand the Technical terms to interpret the Forensic evidences.
- Preparation for final Arguments by connecting the Interpretation of Forensic evidences with the applicable provisions of Law.
- Study of Crime Scene Reports, crime scene photographs, Site Plan etc.
Forensic science of today covers:
- Modern computer/clay facial reconstruction;
- DNA fingerprinting;
- Autopsy techniques;
- Forensic anthropology;
- Toxicology and much more.
Types of Evidence:
- Biological Evidence
- DNA Evidence:
- Trace Evidence:
- Currency Notes
- Driving License
- Pan card
Psychological evaluation is regarded as the key to human brain in crime investigation. There are certain steps to be followed in psychological evaluation, which includes:
- Psychological profiling
- Psychological assessment
- Brain Electrical Oscillation Signature Profile (BEOS)
Types of crime scenes
Collection of evidences
Maintenance of Crime Records
Study of Crime reports
Cyber Forensics: It is the art and science of applying computer science to aid the legal process. Although plenty of science is attributable to computer forensics, most successful investigators possess a nose for investigations and a skill for solving puzzles, which is where the art comes in. - Chris L.T. Brown, Computer Evidence Collection and Preservation, 2006.
Common types of Cyber Crime in India:
- Financial Crimes
- Cyber Pornography
- Sale od illegal article
- Online gambling
- Intellectual Property Crimes
- Email Spoofing
- Cyber Defamation
- Cyber stalking
Steps involved in Cyber forensics:
- Identification: identify the media to be seized
- Seizure: use the right technique to seize the media
- Acquisition: making a forensic duplicate of the media
- Authentication: validation of forensic duplicate
- Analysis: techniques to look for evidence
- Presentation: putting together all the findings
- Preservation: storage of the suspect media
It is a science embodying the knowledge, source, character, fatal effect, lethal dose, analysis of poisons and the remedial measures.
It is a substance which is capable of producing injury or death to living beings, when ingested or absorbed. Eg: LD 50 (Lethal Dose): It is a dose of a substance causing death of 50% animals. Extremely toxic substance weighs less than 5mg
Conclusion: Forensic science plays an integral role in the criminal justice system. Well-trained forensic scientists and medical examiners can be the determining factor in the ability of evidence to adequately represent the facts of a case. Forensic science can be used in almost any criminal case; however, investigations of homicide, rape, and arson are those that benefit the most from forensic science. Everyone is familiar with the television show “C.I.D.” While this show involves a lot of idealism, and often times skews the reality of forensic science, at its core “C.I.D. represents the importance that quality forensic science can play in a complicated case. In complicated cases, and even in relatively simple ones, the most minute of details can become paramount to a successful prosecution or defence. Forensic scientists are trained to analyze crime scenes, evidence, and personal testimony to create a visualization of how a crime occurred. An understanding of the circumstances surrounding a crime is pivotal to ensuring that the correct charges are brought against the correct person. The mishandling or misinterpretation of evidence can be devastating to the goals of the criminal justice system and can result in the wrongful conviction of innocent persons and the failure to convict the true perpetrator, which is why you need a skilled criminal defense lawyer in Knoxville if you’ve been convicted of a criminal offense. Conversely, correctly applied forensic science ensures that justice is served, and innocent persons remain free.
