Forensic Field

Forensic Pathologists: Forensic pathologists play a critical role in determining the cause and manner of death through autopsies, collaboration with specialists, and court testimonies. States differ in their systems—some use medical examiners (physicians), while others rely on coroners (not always physicians). Certification in forensic pathology is essential to avoid errors in complex cases.

As I’m getting lots of queries regarding the screening criteria of the FACT Plus exam, I thought I’d share what I think based on the official notice—but please keep in mind, this is just my interpretation and not a definitive statement. According to the recruitment notice, the FACT Plus exam qualification is part of the screening criteria for eligible candidates. The exact wording is: "The screening criteria of eligible candidates will be on the basis of FACT Plus exam qualification during last three years." So, from this statement, it appears that having the FACT Plus qualification is necessary to pass the initial screening stage. In other words, it seems mandatory to meet this criterion in order to be considered. However, again—this is just my opinion. It’s important to consider a few things: It’s described as a screening criterion, meaning it's likely used to filter candidates at the beginning. Other aspects like interview performance, educational background, and work experience will still play a role in the final selection. Context can influence application of criteria. If the number of applicants is high, they may strictly stick to every criterion during shortlisting. But if there are fewer applicants, there might be some room for flexibility. So, while having the FACT Plus qualification definitely strengthens your position, I wouldn’t treat it as a black-and-white rule unless further clarification is provided by the recruitment body. Hope this helps clear things up a bit!

Key Figures in Fingerprint: Sir Francis Galton: His research established the foundation of modern fingerprint science. Sir Edward Richard Henry: He developed the Henry Classification System. Juan Vucetich: Pioneered the use of fingerprints in criminal investigations. Dr. Henry Faulds: One of the first to recognize the potential of fingerprints for identification. Sir William Herschel: First to use fingerprints for identification purposes in India

Rifled Firearms: 1. Spinning Projectile – The grooves (rifling) in the barrel force the bullet to spin, increasing accuracy and stability. 2. Longer Range – Because of the spin, bullets from rifled barrels travel farther with better precision. 3. Unique Markings – Each rifled barrel leaves distinctive striations on a bullet, aiding forensic identification. 4. Used in Military & Hunting – Rifled firearms like rifles and handguns are preferred for precision shooting. 5. Higher Recoil – Due to higher velocity, these firearms often produce stronger recoil. Smooth Bore Firearms: 1. Shotgun Spread – Smooth bore firearms fire pellets (shot) that spread out, making them effective for close-range targets. 2. Easier to Manufacture – Without rifling, these barrels are simpler and cheaper to produce. 3. Used in Law Enforcement – Shotguns are popular for riot control and police operations due to their spread effect. 4. Slugs Can Be Used – While mainly designed for pellets, shotguns can also fire slugs for increased range and power. 5. Less Accurate Over Distance – The lack of spin means projectiles lose stability at longer ranges.

The parts of a cartridge and how they work are as follows: 1. Cartridge Case: The container that holds all the other components together. 2. Lead Bullet: The projectile that is fired from the gun. 3. Primer: The component that ignites the gunpowder when struck by the firing pin. 4. Gun Powder: The propellant that burns and creates gas to force the bullet out of the barrel.

Key Case Laws in Forensic Science in India 1. Kishore Chand v. State of Himachal Pradesh (1991) Key Principle: The Supreme Court emphasized the importance of maintaining the chain of custody and proper documentation of forensic evidence. It ruled that any break in the chain could lead to questions regarding the credibility of the evidence. Impact on Forensic Science: This case reinforced the necessity of preserving the integrity of forensic evidence from collection to presentation in court to ensure its admissibility and reliability. --- 2. Murugan v. State of Tamil Nadu (2011) Key Principle: The case highlighted the significance of DNA profiling in criminal cases. The Supreme Court upheld the conviction based on DNA evidence, recognizing its accuracy in establishing biological relationships and involvement in crimes. Impact on Forensic Science: DNA evidence gained legal recognition as a highly credible and scientifically sound tool, strengthening its role in criminal investigations and prosecutions. --- 3. Selvi v. State of Karnataka (2010) Key Principle: The Supreme Court ruled that narco-analysis, brain-mapping, and polygraph tests violate the right against self-incrimination under Article 20(3) of the Indian Constitution if conducted without consent. However, these tests may be used as supportive evidence when voluntarily undertaken. Impact on Forensic Science: While these techniques remain valuable for investigations, their use as direct evidence in courts is limited due to concerns over constitutional rights and voluntariness. --- 4. State of Gujarat v. Kishanbhai (2014) Key Principle: The Supreme Court stressed the importance of accurate forensic examination and criticized lapses in handling forensic evidence, emphasizing that negligence in forensic analysis can lead to miscarriage of justice. Impact on Forensic Science: This case reinforced the need for meticulous forensic investigations, proper documentation, and timely forensic reports to ensure fairness in criminal trials. --- 5. Maneka Gandhi v. Union of India (1978) Key Principle: Although not directly related to forensic science, this case emphasized the significance of due process and personal liberty under Article 21 of the Constitution. It set a precedent that forensic techniques must align with constitutional protections of individual rights. Impact on Forensic Science: The ruling serves as a reminder that forensic procedures, including evidence collection and examination, must respect due process and the fundamental rights of individuals involved in legal proceedings.
