1.1 – Evaluate the effectiveness of roles of personnel involved in criminal investigations
Police Officers
Usually the first to arrive on the scene, police officers' primary goal is to protect the public by
apprehending potential suspects and protecting the crime scene. Yellow tape, which deters
unauthorised individuals from approaching the crime scene or corrupting any evidence, is one
method they use to protect the crime scene. They need to speak with as many witnesses as they can
after the crime scene has been located, and they try to do this during "the golden hour." The time
immediately following the murder scene's discovery is known as the "Golden Hour." In order to solve
the case, authorities must gather as much evidence as they can and obtain the most reliable eye
witness testimony.
One advantage of police officers is, they have specialist training for their job role, they must finish a
training programme that includes handling several crime scenes to guarantee they are qualified for
the position. This training enables cops to hone a variety of abilities, including evidence recognition
and teamwork, both of which are essential at a crime scene. Another benefit of this position is that
the testimonial evidence they compile can be trusted in court and used to make a final decision. As a
result, they occasionally have a significant impact on advancing justice. Police officers have the
reputation for not looking into crimes like burglaries and domestic violence because it is more
difficult to convict someone of these. Instead, law enforcement favours cases with high chances of
success, including homicide or manslaughter. Another disadvantage is that police officers also have
the drawback of occasionally handling circumstances improperly, which jeopardises the integrity of
the entire investigation. As an illustration, consider Stephen Lawrence, an 18-year-old man who
suffered two chest stab wounds. Since they believed it was too late to rouse anyone awake when
the police came, none of the cops provided first aid or made inquiries door-to-door. Due to the
appalling way this case was handled, the courts concluded that Stephen Lawrence was the victim of
institutional racism on the part of the police.
Crime Scene Investigators
The CSI's primary responsibility is to record the scene. Before collecting any physical or biological
evidence, the CSI took images and recordings of the occurrence, which can be used as independent
proof. The CSI's next task is to gather as much evidence as they can after the scene has been
photographed and described. They specialise in gathering biological and physical evidence, including
fingerprints, body fluids, and blood. However, it's crucial to avoid tainting the evidence when
gathering it. By donning protective gear like face masks, boot covers, gloves, goggles, and protective
suits, the CSI avoids contamination. Once all of the evidence has been processed, it can be used in
court. Additionally permitted to attend postmortems is the CSI.
An advantage of the CSI is that it has the benefit of having excellent communication with all other
professionals engaged in criminal investigations. Since the police arrive first at a crime scene, they
collaborate closely with them so that when the CSI shows up, they can ask some preliminary
questions before gathering information. Additionally, they might consult forensic scientists to review
the evidence they found. Another asset of the CSIs is that they have had specialised training to get
credentials and are typically degree-educated in a scientific field like chemistry or forensic science.
With this specialised training, they are able to present any evidence they gather in court. Physical
evidence gathered by a CSI can be crucial in criminal cases and could make the difference between
life and death. Although a CSI takes efforts to prevent evidence contamination, evidence might still
be corrupted while the CSI is gathering it. Consider the "Phantom of Heilbronn," who was once
regarded as the most deadly woman in Germany. She has been implicated in 40 crimes, including
