Physical Surveillance EssayThe act of control is designed to observe individuals, surface firmaments or objects that are of item interest to an investigator in order to collect information and demonstrate that may be associated with a suspect and his related criminal activities. Physical surveillance is a method of examination of a particular area that is linked to a plague scene or a suspect. This may include inspecting the area when the crime took place, as well as the victims and suspects homes, vehicles and paraphernalia. Examination will cover both the conditions of the places and items, as well as the position of the places and items in the particular areas. Physical surveillance is important in a crime scene investigation because it provides a way for the investigator to rejuvenate the scene and make inferences on what actually happened during the incident (Gardner, 2005). Any area that is associated with a crime is identified as soon as a crime has been establishe d or reported.In addition, these particular areas are protected from whatsoever type of disruption by putting a crime scene record along the perimeter of the area concerned. It has been reported that the most complicate part of an investigation is the establishment and protection of the boundaries of a crime scene because the signs related to a scene are often elusive to an investigator. Other investigators employ search dogs to facilitate the establishment and tracking of a crime scene. Photography is commonly apply in the physical surveillance of a crime scene.This visual documentation of an area is very helpful to an investigator because it physically records the features of the area before any other activity is performed to the crime scene. Physical surveillance in addition involves marking all potential evidences to the crime. In addition to photographs, sketches of the crime scene are to a fault important in physical surveillance of a specific area. Sketches are generally considered as essential information of crime scenes because these serve as expatiate notes of the investigation, although the diagrammatic representation is of less quality than a simple photograph.Sketches provide measurements of the crime scene, including distances between two points of interest that are located within the area under investigation. An investigator often starts with a rough sketch and eventually moves on to a final sketch that is drawn to scale. These sketches are commonly occupied as models during court hearings and trials because these provide the floor-plan of an area of interest, the elevation of the area and its details and other critical dimensions that may be helpful in the analysis of a crime scene.Physical surveillance serves more purposes in a crime scene investigation than a technical surveillance because it provides the investigator with sufficient evidence that may be important in linking a specific suspect to a particular crime. Technical surveilla nce does not provide the specific details that physical surveillance provides because it does not provide any associative details that are critical to an investigation.In addition, physical surveillance provides a view of the crime scene through an observers eyes and this usually provides a neutral view of the area, removing any biases and discrimination of certain items and areas. Physical surveillance also provides a better understanding of a crime incident through the note-taking that is performed on the area, including any traces of struggle or bullet holes. It also assists the investigator in reconstructing the sequence of events that are related to the crime, including the initial moments of what was said, done or executed by the victim and the suspect.
