2. Technological Revolution:

• Then: Communication was limited, with police relying on rudimentary methods like call boxes and teletype machines. Record-keeping was manual and time-consuming.
• Now: Technology is integral to every aspect of policing and investigations. Computers, databases, and the internet allow for rapid information sharing, crime mapping, and data analysis. Body cameras, surveillance systems, and drones provide real-time monitoring and evidence collection. Cybercrime has also emerged as a new challenge, requiring specialized skills and tools to combat.

3. Community Policing and Problem-Oriented Policing:

• Then: Traditional policing models focused on reactive responses to crime, with limited interaction with the community.
• Now: Community policing emphasizes building relationships with residents, addressing the root causes of crime, and working collaboratively to solve problems. Problem-oriented policing takes this further by focusing on specific crime patterns and utilizing data-driven strategies to prevent crime. These approaches recognize that police effectiveness is enhanced by community trust and engagement.

4. Increased Professionalism and Training:

• Then: Police training was often inadequate, with little emphasis on legal procedures, ethics, or community relations.
• Now: Police academies provide extensive training in areas such as criminal law, investigation techniques, use of force, and cultural sensitivity. There is also a greater focus on officer accountability and ethical conduct, with increased scrutiny of police actions.

5. Shift in Focus:

• Then: Policing was primarily focused on reactive crime control, responding to incidents after they occurred.
• Now: There is a growing emphasis on proactive policing strategies, such as intelligence-led policing, predictive policing, and hot-spot policing. These approaches utilize data analysis and technology to anticipate and prevent crime before it happens, allowing for more efficient resource allocation and targeted interventions.

These five changes represent a significant evolution in policing and criminal investigations. While challenges remain, these advancements have led to more effective crime fighting, increased accountability, and a greater emphasis on community engagement.
