Forensic science role in solving judicial cases

The application of science to the law is known as forensic science. Forensic analysis key role is to investigate and prosecute civil and criminal cases. It can aid in determining the guilt or innocence of potential suspects.

Its goal is to advise individuals conducting criminal investigations and provide correct information to courts to resolve criminal and civil issues. Forensic evidence is primarily utilized to connect crimes suspected to be linked. DNA evidence, for example, might link one perpetrator to a number of different crimes or crime sites, or it can exonerate the guilty. Forensic evidence also assists in connecting crimes assisting law enforcement officials in narrowing the spectrum of probable suspects and establishing patterns of crime that may be utilized to identify and prosecute individuals. 

Forensic scientists, primarily utilised in criminal cases, deal with the search and investigation of physical traces used in establishing a suspect of creating a crime at the site of the crime or of the victim. This might include blood traces or bodily fluids, as well as clothing and materials.

A forensic expert, such as a scientist from any technological discipline, will give evidence analysis, witness testimony on examination results, technical support, and even training in his or her specialized area. Its goal is to provide advice to those conducting criminal investigations by recognizing and retrieving evidence at crime scenes and reliable information on which they may rely to settle criminal and civil issues. Murder, rape, accident-related occurrences, unidentified individuals, displaced persons, fraud-related instances, and forgeries are all examples of crime.

Forensic science also encompasses everything vital in gathering, preserving, and analysing evidence, such as DNA identification, structural design study, and explosive identification. Statements and witnesses are utilised as evidence in India, and those found guilty are penalised. As a result, forensic science services may become the essential crime-fighting tool for law enforcement.   

A wide range of forensic science and forensic resources are used to investigate a criminal crime. Throughout the criminal investigation, evidence is gathered from the crime site or by an eyewitness to the entire occurrence, which is subsequently analysed in a forensic lab, and the findings are given to the court. Every criminal investigation is unique in its way and has its own set of obstacles. Forensic science plays an important part in the criminal justice system by providing scientifically based information through the investigation of tangible evidence, such as fingerprints, footprints, blood drops or ears, cell phones or other gadgets, autos, and arms.

In both criminal defence and prosecution, trial attorneys and lawyers employ forensics to prove and refute the evidence they present in court. For example, when there are no witnesses for the crime committed, the prosecution can gather DNA evidence obtained at the crime scene in the defence. Forensics may even show when a crime occurred — down to the minute and hour. Forensics can also be utilised to ascertain the cause of death, which can provide investigators with information on the murder weapon to seek and, as a result, a starting point for their search for a suspect.

Drug-related crimes and sex crimes are two of the most prevalent crimes investigated with forensic technology. Forensics can be used in drug offences to ascertain the chemical makeup and hence whether or not an individual had illicit narcotics. Suppose the findings show that an individual has used illegal substances. In that case, the prosecution can use the results as evidence to prosecute them for anything from drug possession to drug production or trafficking. In the case of a poisoning death, forensics can be utilised to establish the drug used to kill the person and restrict the list of suspects by determining who would have access to such chemicals. In sex-related offences, DNA from the victim may be extracted, and the findings analysed is used to convict the perpetrator. 

The judicial system is well aware of the importance of forensic evidence in criminal proceedings. This is because adopting scientific methodologies and approaches leaves little opportunity for bias or discrimination. This is why DNA profiling and other forms of forensic evidence are widely accepted in courts across the world. Surprisingly, the Chinese (650 A.D.) invented the first forensic procedure incorporating fingerprint identification.

Forensic testimony is extensively utilised in condemning and exonerating suspects worldwide. As a result, forensic science labs have sprung up all over the world in recent decades. In addition, Special Acts have been introduced in the United States, Canada, and Australia to improve the delivery of forensic services. This increases the certainty with which crimes are detected, and as a result, conviction rates may rise. Such Acts place a high value on crime scene management, both prompt and high quality. Forensic evidence is often utilised for both guilty and acquitted offenders. As a fact, the number of crime laboratories worldwide has expanded dramatically over several decades. India established the first governmental crime laboratory in 1878. There are currently 35 forensic labs that only deal with one-of-a-kind facts. The expanding rank in forensic sciences and the critical role that forensic evidence plays in many criminal trials has increased the number of criminal labs.

In the Indian case, more emphasis was placed on the application of these technologies in criminal investigations and trials. Commissions on criminal justice reform have said that crime detection technology will allow the system to function more efficiently. As per the advancements, the relevant laws have been amended from time to time to accommodate the use of forensic technology in the investigation and prosecution of crime. Nonetheless, it might be claimed that the regulations that need to be altered now contain problems. Furthermore, because of their conservative attitude, judges are hesitant to depend on empirical evidence or other inherent faults in the material given in court that prohibits them from relying totally on it. The basic goal of the criminal justice system is to provide equitable justice. Without a doubt, forensic evidence is more believable than eyewitness testimony. Currently, forensic science plays a vital role in crime prevention and detection. The basic clause of the criminal justice system is to provide fair justice. Forensic science is advantageous to the criminal justice system as scientific evidence.
