Forensic science is just one study of legal issues and the pursuit of answers to legal questions by applying scientific knowledge and technology. There are two specific cases where the legal system becomes involved, first, when private parties, such as businesses, need facts to support such civil action lawsuit. The second example occurred when a crime is suspected or have been made. Now, in both cases, a forensic investigator, or rather a forensic science practitioners should examine the resources available today to discover the facts that are supported by the available resources. And more than that, the fact help answer questions expected or required by law system.
There the difference between an investigation initiated in the private business sector differs significantly from investigations initiated by public officials for criminal investigations. The most significant difference is the possible effect of the probe. Private investigations could potentially result in any or all of the following events:
Loss / gain of money or goods
The loss or maintenance work
Potential disciplinary action
The most common reason for investigation in the public sector is a criminal activity has the potential to imprison citizens. In some cases, a public inquiry will involve the obligation of public officials on issues involving public safety and the investigation may result in the loss of public funds paying taxes, or may affect new legislation . Since most public investigations involving crimes and criminals that commit them, the term public inquiry will be used synonymously with the criminal investigation around text.
The monetary costs associated with the legal action is known as a motivator in forensic investigations. In general investigation, prosecution can take years and cost millions of taxpayer dollars in court costs. Suspect the prosecution should have legal defense costs and, although ultimately convicted, the defendant in a legal case may suffer a loss of reputation and work. If the claimant fails to successfully convict the suspect has the right to restitution for damage to reputation or wages. To make matters worse, the suspect may have to pursue private legal action to cover damages resulting costs.
Legal more action in the private sector is not exempt from the monetary motivators. Private sector legal action may extend over several years and cost millions of private funds. In addition to the potential monetary costs, in the case of the private sector tend to bear the high cost in time and inconvenience for all possible participants.
The successful legal action whether it is private or public considerable increases as the level of confidence in truth investigation increase. For example, in the case of private sector frequently check the facts to assess whether the company violated policy or employment contract. With very few exceptions, the public sector investigation involving law enforcement as the investigation resulting from the crime or in cases where the alleged crime was occurred.
Private investigation has revealed the potential for criminal activity. Although the technology and tools to gather the facts of the same or similar to the case of the private and public sectors, the procedure for collecting the two will vary considerably. Despite their differences, the two rules are rarely contradictory, but it will have to deal with all private parties, including forensic investigators, and private attorneys, and local law enforcement and public defenders to keep level of confidence in the credibility of the investigation. Investigators Forensic investigators trained to be a professional to apply forensic science. Apply this knowledge and skills in many disciplines such as geology, physics, chemistry, toxicology and more. Therefore, forensics can be defined as the application of various disciplines to answer legal questions. The first function of a forensic investigator to assess the legality and feasibility of collecting evidence. Nature of the investigation requires the collection and analysis of evidence conducted in full accordance with the law. Both public and private investigations must respect the rights of personal citizens.
Once likely cause is established, calling for the dismissal. With the call for the band, giving law enforcement the right to search for evidence of a specific crime, but only allowed to gather evidence in “plain sight” clear and say the crimes committed . Another forensic investigator function is to support the “tracks in prison” the right of all the evidence collected in a case. Chain of custody is a simple record of what evidence was gathered that, when developed, and you access it. A proper chain of custody is necessary to prevent contamination or even the emergence of evidence of contamination. Chain of custody is equally important to both public and private investigations.
Evidence Whether public or private, the facts of the case appear from the evidence in the investigation. The best evidence is defined as real or short to reveal and prove the objective reality of the investigation. Evidence is usually used to prove the fact that crime has been committed, the suspect did or did not commit the crime, the sequence of events during the motives crime: The method of proof may include, blood evidence, trace evidence material, fingerprints, personal or personal records, public records, drug content, evidence control, identification and testimony.
During investigation, two very different roles in the emerging field of forensics. The first role is the collection of evidence. This role requires a relatively limited experience, training and qualifications. An investigator in this role is often to travel to crime scenes or evidence could be called to prepare for the second paper. The second paper is the study of evidence. Here, evidence is reviewed, assessed, and studied for the facts and conclusions.
