The difference between lead and principle investigation is the nature in which the investigation is undertaken. Therefore, it is ideal to consider that this adds to a proper understanding of the two approaches of criminology. Investigations are the processes that will be used to describe both criminal investigation and crime scene processing distinctions between criminal investigations and crime scene. Crime scene requires strict scientific methodologies such as collections procedures and testing protocol, whereas criminal investigation has less of hard science character and relies more on the experience and skills of the investigator rather than rigid scientific protocols and procedures. Evidence is a piece of information that supports cases in the trial likes the testimony and presentation of documents, records, objects and other such items relating to the existence or non-existence of alleged or disputed facts into which a court enquires. Evidence is also designed to ensure that evidence which has been compromised is not accepted. Make sure that the evidences must be credible and competent. Investigation involved describing or quantifying parts of natural or manmade systems. There are several types of investigation that will became part of your routine as an investigator which are criminal investigation, civil investigations, negligence investigations, corporate investigation, general investigations, personal and backgrounds check and security. Firstly, criminal investigation is an applied science that involved the study or facts, use to identified, locate and prove the guilt or a criminal. A complicit criminal investigation can include searching, interviews, interrogation, evidence collections and preservation and various method of the investigation. Furthermore, modern day criminal investigations commonly employ many modern scientific techniques known collectively as forensic science. Private investigators work either for the victims or for the defendant or his attorney in criminal proceeding.
Lead investigation attempt to solve criminal acts through intelligent means. These investigators rely on criminal intelligence to influence law enforcement in the reduction and prevention of crime. Investigators present officers with intelligence briefings in presentations and reports gleaned from wire tapings, surveillance and other means (Palmiotto, 2012).
Lead investigation in criminal cases collect information from both witnesses and suspects. They comb the crime scene for potential clues, such as physical evidence, fingerprints, DNA and more. To document the scene they may take photos of the crime scene or rely on high-tech devices such as Leica scanners, which preserve the crime scene in a 3D render that captures every detail.
It takes a certain set of abilities to accomplish the tasks of Lead investigation. To this end, they must be knowledgeable of federal, state and local laws concerning police operations, evidence custody and destruction and investigative procedures. They need knowledge of narcotics investigations, including surveillance and covert purchases. An understanding of information technology pertaining to criminal investigations is a must, as is the ability to report clearly in both oral and written reports.
Investigators occasionally perform physically strenuous tasks, reinforcing the need for basic physical fitness. Lead investigation must be able to perform simple tasks, such as standing, kneeling, crouching, crawling, reaching and more. Further, they should be able to exert up to 100 pounds of force and pass an eye exam necessary to operate a patrol car and distinguish details in crime scenes, people and places.
Other duties the lead investigator performs include taking evidence, maintaining records, processing evidence and submitting evidence to courts. What’s more, they occasionally have to purchase supplies and materials needed for investigations, such as identifications equipment. Investigators also maintain the stock of supplies. The lead investigator may also serve as a patrol officer responding to calls when needed, or he may perform traffic and evacuation duties if necessary.
The Principle investigation is central to administrative procedure. Pursuant to this principle, an administrative authority is required to establish the facts relevant to the matter – both favorable and unfavorable for the participants in the procedure, as well as those relating to the public interest – and, if necessary, collect evidence on its own initiative for such purpose. Public authorities are also obligated to act where facts relevant to the matter are not precisely known.
Decisions made in procedures aimed at the prevention of unwanted events are by nature decisions based on probability. In such procedures, it cannot be expected that all relevant facts will be fully established or undeniably proved as they relate to events that may occur in the future and the occurrence of which can only be predicted. Administrative authorities have a wide margin of appreciation in the interpretation of undefined legal concepts and the evaluation of evidence. Consequently, implementation of the Principle investigation may vary significantly in different subject areas, depending on the nature, objectives, and legal regulation of the area.
The Principle investigation is central to administrative procedure. Pursuant to this principle, an administrative authority is required to establish the facts relevant to the matter. Lead investigation attempt to solve criminal acts through intelligent means. I conclude that the difference is clear that the procedure amid the two is what creates the big difference. From the overall explanations, an investigation is important to identify suspect, find the different factors on how the incident can be happen and solve the incident quickly. Identify the suspect is really important because the suspect is the responsible person who do the crime. If not, it may cause generous situations by let the suspect with public. By doing so, investigator will need evidence and witness in order to solve the crime. Once the evidence was found, evidence will be submitted to the crime laboratory to review in detail. Then, witness also important in the investigations to get more information and data to look up how the real situation of the crime happens. Investigation bust-outs may be discouraging; however, a lead investigation is the type of investigation that poses the type of intellectual challenge that made many individuals become investigators in the first place.
Because the principle investigation is so difficult and resource-consuming, and with little hope of financial recuperation, it is best for your employer to stop the principle investigator before he gets in the door. The investigator should educate the credit and sales departments of his employer about the warning signs of a principle investigator; they can serve as the first line of defense against the bust-out operator. Like any con man, if the bust-out operator encounters resistance at the beginning he will simply go to another victim
