Cole and Michael Lynch stated that “Forensics is the “silent witness,” it “never lies,” and it cannot misremember or be biased or bribed.” “Forensic science is often seen as an applied science used in criminal investigations and criminal trials.” Not only, a minor crime but also serious crimes, the DNA technology can help to identify criminal problems of the United States and the world such as transnational crime, terrorism , and illegal migration. In Thailand, the DNA technology has shown a major role in important events in the country.
Without a motive, it would be difficult to prove guilt since the number question needed to be answer for juries are the “whys” in crimes. Therefore, it is extremely important to establish a motive in a case that a jury would believe. In addition, it is also important for criminal investigation personnel to collect and interpret evidence correctly to establish an accurate motive. The Behavioral Evidence Analysis would be the most effective method help with this. Behavioral Evidence Analysis (BEA) is a deductive based strategy that uses evidence from an investigation to determine the offender’s personality and behavioral characteristics.
1.Polymerase chain reaction (PCR): Polymerase chain reaction is a method of DNA or RNA amplification . The PCR method allows millions of copies to be created from a very small DNA section. The PCR methodology was developed in 1983 by Kary Mull , who in 1993 received a Nobel Prize for Chemistry with Michael Smith PRINCIPLE & PROCEDURES: 1.DNA denaturation. Once the DNA has been isolated and purified from the cell, a PCR assay can begin. Uncleaned DNA can also be used for PCR, but it is ineffective.

Too much insistence upon procedure some time may lead to acquittal of the accused and impunity on the offence. The judge in the court as an umpire is a misleading conception since one only judges according to the evidence submitted in court.
Sometimes a criminal investigation may not produce any further leads causing the case to be set aside. This is why the investigator utilizes twelve essential questions to guide the investigation and determine the solvability of the case. This is also why the investigator works closely with prosecutors to determine the solidity of a case and whether to bring the suspect to
The law is well settled that each and every incriminating circumstance is required to be clearly established with supporting evidences and also the chain of events should be complete in such a manner that the only conclusion which could be drawn is guilt of the accused and no other hypothesis against the guilt is possible. The Supreme court also didn’t hesitate in giving death sentence to the murderer only because the case relied on circumstantial evidence. The general rule is that it is admissible in a court of law but they are required to be cautious when a case solely relies on circumstantial evidence. All the facts should be closely examined and it must be looked at
Criminal Investigative Analysis, also known as criminal (offender) profiling, is an investigative tool which is used within the law enforcement community to help solve violent crimes. According to Canter (2005), an investigative psychology describes a framework that integrates several range of aspects in to all contexts of criminal and civil investigation.The analysis is based on a review of evidence from the crime scene and from witnesses and victims. The analysis is done from both an investigative and a behavioural perspective. The contributions that psychologists can make to police investigations are most widely known and understood as this offender profiling. Offender profiling, as typically practised, is the process by which individuals,

The concept of jury nullification is not one that is broadly known or spoken about in the discipline of law. This is because until more recent years the concept was considered a complex subject that garnered plenty of conversation and debate. To understand the controversy that surrounds this particular area of the law, a definition of jury nullification is in order. It is known that the jury’s role is to act as the unbiased and impartial voice of judgment during the proceedings of a court case. They are required to listen to all sides of the story, examine all facts presented, and are ultimately responsible for reaching a verdict of either guilty or not guilty.
Each case wasn’t just set in modern day America, some cases dated all the way back to the 1800s showing the origins of some techniques. The case studies were engrossing, especially since they didn’t all happen in the same place. Individually, the chapters would open with a brief summary about what an expert in that particular field of Forensics would do on a typical day at work. Cases were summarized just enough, while still highlighting the importance of Forensic science in each one. For example revealing the differences between methods such as the difference between chromatography and spectrometry, two important techniques.
