¶ … obstacles to prompt and efficient forensic investigation in major crime scenes. The presence of too many unnecessary personnel in the crime area and poor communication or reporting of the details are these obstacles. The applicable FBI rules and an analysis of each issue follow. A conclusion is also provided for each issue. Too Many Unnecessary Personnel at the Crime Scene

The presence of too many extraneous personnel is considered the biggest hindrance to effective and prompt crime investigation (Schiro, 1999). What makes it worse is that most of these unnecessary people are police officers themselves (Schiro).

Rule

The policy mandates the initial responding officer or officers to identify all personnel or persons at the crime scene and to oversee their movements (FBI, 2000). Then the officer or investigator in-charge shall evaluate the scene in order to come up with a list of specialized resources needed in the investigation (FBI).

Analysis

Protecting the crime scene is a major function of the said officer or officers (FBI, 2000). He should supervise the movements of all the persons in the area. They should be prevented from changing, moving or destroying any physical evidence. They should be accurately identified as suspects, witnesses, victims and families or friends, assisting police personnel or mere bystanders. The latter and all other unnecessary persons should be told to leave the area (FBI).

Determining the composition of the investigation team is the first step in processing the scene (FBI, 2000). The decision shall be...

Only trained personnel shall handle the processing. The investigator should first conduct a walk-through and then follow an orderly procedure. He should determine if additional personnel are needed. This immediately solves the problem of having too many of them in the crime scene. If additional ones are needed or desirable, particularly in cases of several crime scenes, several victims, witnesses or complex circumstances, the investigator should be keenly aware of their respective needs. He should simultaneously be aware of forensic needs and call in specialists for their expertise or special equipment to the crime scene. He should also secure the scene and the sustained passage of documentation work. From the selected team, he should choose those who shall perform special functions, such as photography, drawings, prints, or collection of evidence. Then the investigator shall be promptly informed when these special tasks are completed (FBI).
Conclusion

Limiting the number of persons in the crime scene and controlling their movement are necessary in preserving and safeguarding evidence from alteration, destruction and contamination (FBI, 2000). The investigator assesses the necessary number of personnel who should be in the crime scene and their respective assignments (FBI).

A crime scene debriefing team should also be constituted (FBI, 2000). It shares scene findings before releasing the scene and provides inputs for follow-ups, requests for assistance, and other post-scene requirements. It determines evidence…
