By providing impartial, scientific evidence, forensic methods protect individuals from
wrongful convictions, reduce reliance on coerced confessions or torture, and strengthen
the right to a fair trial. They also uphold the dignity of victims by identifying missing
persons, restoring the truth of state abuses such as enforced disappearances, and
ensuring accountability in cases of extrajudicial killings or custodial deaths. Thus, forensic
science functions as both an investigative tool and a guardian of fundamental human
rights.
Literature Review
In his book, “Forensic Science- An Introduction to Scientific Crime Detection”, Wall
(2008) presented an extensive and update understanding of the overall context for
expert scientific evidence as well as how scientific methods are applied in the
administration of law, particularly in the criminal justice system. The author without
assuming any scientific background on the reader’s part, has thoroughly discussed every
advancement in technology in the field today. Lee & Pagliaro (2013) explained that, by
using forensic methods and plan of action, advance law enforcers have remarkably
increased their capacity to resolve crime offences. In present scenario, cases can often
be solved with forensic evidence investigation and a thorough and careful crime scene
examination. Forensic scientists play a vital role not just in criminal investigations and
prosecutions but also in civil litigation, major natural and man-made disaster relief
efforts, and the investigation of transnational crimes. Forensic evidence analysis requires
a team-oriented system, advanced investigative tools and methods (such as GPS
tracking, cell phone tracking, video image analysis, artificial intelligence, and data
mining), and the ability to properly process a crime scene by locating, obtaining, and
preserving all relevant physical evidence.
Rudin & Inman (2000) have proposed that reconstruction, or attempting to help
ascertain the causes, process, timing and place of the incidence or criminal act and the
associated or engaged offenders, is at the core of science's application to the legal field.
evidence that has undergone forensic investigation to help the court establish tangible
facts to settle a criminal or civil issue.
Further, Irons & Lallie (2014) identified the importance of digital forensic and suggested
that, the ability of digital investigators to apply digital forensics and investigative
procedures to obtain timely results is under increasing strain due to the rise in
cybercrime, the complexity of the various types of cybercrime, and the constraints on
time and resources—both computational and human—when addressing cybercrime. The
limitations and capabilities of the forensic tools currently in use must be overcome to
better utilise the resources at hand and address the issues.
According to Hollien (2002), voice-based evidence is a crucial component of many
criminal investigations and frequently consists of recordings made during police
questioning, robberies captured on camera, or threats left on an answering machine. In
the era of mobile phones, voicemail, and speech recognition software, technology is
everywhere. The book emphasizes strategies and procedures for assessing recorded data
and aids in understanding the fundamental sciences underlying voice recognition along
with exacting analysis of the scientific data regarding how well crime prevention works
in the US, the UK, and other countries. It examines over 600 scientific assessments of
