1POLICINGAssessment Criteria2.1 - describe the investigative process, including relevant activities and decision making One of the primary aspects of crime scene investigation is properly providing an initialresponse to the crime scene. The process of initial response includes ensuring that there isminimal disturbance and contamination of physical evidence within the crime scene. Thereshould always be a methodical and expeditious initial response to an incident. Upon arrival theinitial officer has to assess the situation and treat it in form of a crime scene. There should be aprompt but cautious approach towards taken by the officer while entering the crime scene (VanSteden et al. 2015). They should remain observant of any event, vehicle, environmentalconditions, potential evidence and person. The initial officer is required to log or note dispatchinformation such as parties involved, type of call, time, date and location. They should be awareof any vehicles or person leaving the crime scene. Scan the total area cautiously and take a noteof a possible secondary crime scene. The officer has to initiate observations for the purpose ofassessing the scene and before proceeding take into consideration officer safety. The locationhas to be treated as a crime scene until it has been determined otherwise (Young et al. 2013). The officers have the duty to properly preserve the evidence and crime scene. It is theduty of the officer to treat the crime scene with utmost care and not to contaminate or destroy theevidence. The officers have to at least establish a perimeter for the purpose of protecting thecrime scene. All people who may not be involved in the incident have to be evacuated (Bacon2014). People not having authority have to be prevented from entering or contaminating anyevidence at the crime scene. The officers have to prevent any damage or further damages whichmay take place in relation to the incident. The officers with respect to preserving the evidence
2POLICINGmust not alter the position of anything unless is required absolutely. The scene and evidence hasto be photographed properly before anything is altered. Any evidence which has been identifiedor moved has to be recorded in relation to where, what, when and by whom. Each piece ofevidence has to be kept separate from other evidence in order to avoid cross contamination.Paper bags needs to be used for blood-stained items (Baldry and Sebire 2016). In the samewitnesses have to be isolated from each other and other and their statement has to be recorded inobservation or statement report. The officers should ensure that they utilize specialist services inrelation to the investigation process such as SOCO and forensics. This would help theinvestigation process to be more accurate as there would be little chance of evidencecontamination. The investigation process must also include conducting interviews of anyidentified suspects who are present at the incident (Chaulk, Eastwood and Snook 2014). The decision making required in relation to progress of an investigation process is crucialto the success of the investigation. The officers have to indulge in rational and appropriatedecision making as to what should they do in relation to the crime scene and who are to beinvolved further. These decisions may be in relation to moving any piece of evidence whichmay be required, choosing the people who are likely to be involved in the incident in from ofsuspects, decision to involve other departments such as forensics, SOCO and intelligence(Bazemore and Schiff 2015). In case decisions are not taken appropriately in relation to thecrime scene it may have a considerable adverse impact on the investigation process. For instancein case the officers does not involve the forensics at a proper time the evidence in relation to thecrime scene may not be collected in a proper manner and thus its acceptability within the courtwould be challenged. In addition there are chances that without forensics being involved theevidence may be altered (Crank 2014).
3POLICING2.2 - explain what information is required to support investigations An investigation is done by investigative officers in relation to criminal activities.However the investigative process and the result obtained through it is alone adequate forproving that the crime has been committed by a specific person. The actual prosecution of suchsuspect is done in the court. Here the judges weigh the evidence provided to them by both theparties to the case and come to a conclusion that whether the crime has been actually committedby the suspect or not. The court base their judgement of the principle that it is better to let acriminal be free than to prosecute a criminal. The prosecution must therefore prove beyondreasonable doubt that the suspect is the one who has committed the crime. In order to do this theprosecution relies upon the evidence collected and processed through the investigative process(Gerstein and Prescott 2014.). On the other hand the defendants provide arguments against the prosecution to prove thatthere is no involvement of the suspect in relation to the crime. This is done by the defendantattorney by challenging the process in which the evidence had been collected by the investigativeofficer against the suspect in relation to its integrity and admissibility in court. Therefore thereare various information required by the prosecution to establish that the evidence has be lawfullyand appropriately collected without any chance of contamination (Dorn et al. 2014). The prosecution has to provide before the court that the evidence which have beencollected in relation to the investigation process is uncontaminated and have not been tampered.This is done by the prosecution by providing the court with the process which have utilized forthe purpose of collecting, storing and analyzing the evidence.
