Page 2: Scene of Crime Officers (SOCOs) and Their Functions
This page introduces the specialized role of scene of crime officers and their critical functions in criminal investigations. SOCOs typically work 42 hours weekly, earning between £16,000 to £35,000 annually.
Definition: SOCOs are specialized officers responsible for collecting and processing crime scene evidence while maintaining its integrity.
Example: The Wembley Park murders case highlights potential failures in police response and misconduct, demonstrating the importance of professional standards.
Highlight: SOCOs require specific qualifications, typically including a degree in forensic science or related scientific field.
The text elaborates on the strengths of crime scene investigators, particularly their specialized training and availability through on-call systems.
Page 3: Limitations and Challenges of SOCOs
The third page focuses on the limitations of crime scene investigators and operational challenges they face in their role.
Highlight: The emotional and psychological demands of dealing with gruesome crime scenes present significant challenges.
Definition: Evidence contamination refers to the alteration or degradation of physical evidence that can compromise its investigative value.
The page emphasizes how proper scene security and timing are crucial for effective evidence collection and preservation.
Page 3: SOCO Limitations and Challenges
The text explores the limitations of crime scene investigators and challenges faced by SOCOs in their work.
Highlight: SOCOs face significant emotional and psychological challenges, especially in gruesome crime scenes.
Definition: Evidence contamination occurs when physical evidence is compromised through improper handling or exposure.
Example: The Meredith Kercher case demonstrates how evidence contamination can impact investigations.
Page 4: Forensic Science Limitations
This section examines the challenges within forensic science and its impact on criminal investigations.
Highlight: Disagreements between forensic experts can complicate court proceedings.
Example: The Greg Taylor case demonstrates how misinterpreted forensic evidence can lead to wrongful convictions.
Definition: DNA analysis is the scientific examination of genetic material for identification purposes.
Page 5: Pathologist Role and Limitations
The text discusses the strengths of pathologists in criminal investigations and their challenges.
Highlight: Pathologists require extensive training, including medical school and seven years of specialized education.
Example: The Sally Clark case illustrates how pathologist errors can impact justice outcomes.
Definition: A pathologist is a medical professional who examines bodies to determine cause of death.
Page 1: Police Officers' Role and Effectiveness
The first page examines the fundamental role of police officers in criminal investigation. Police officers, as first responders, work 37-40 hours weekly with compensation ranging from £21,000 to £41,500 annually.
Definition: Police officers are trained professionals who serve as first responders at crime scenes, requiring no specific qualifications but benefiting from related experience.
Highlight: Key responsibilities include preserving life, securing crime scenes, taking initial statements, and potentially making arrests.
Vocabulary: First responders - Emergency personnel who are first to arrive at an incident scene.
The page details both strengths and limitations of police officers' roles. A significant limitation of police officers involves public perception issues and potential evidence contamination risks.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
