The new century has begun with a milestone in development and technology. With the increasing popularity of internet functions, cyber crime and theft have emerged as new propaganda. Apart from online crime, computer technology has allowed criminals to violate law and order with the help of sophisticated instruments. As such, there must be inclusion of computers and technology in the power of law and order. Now, developed countries like Britain, US, Germany, France, China, etc. Using scientific instruments such as CCTV cameras to detect criminal forces. This became possible only with the introduction of computers. Computers surround all areas of human life.
Virtual reality has become the determining stone in law enforcement. Virtual reality like a 4D movie where you feel almost the same as the original scene that has happened. This helps during the settlement of the case in court where the witness tells the crime scene as detailed as he saw and is being projected on the screen to match the original scenario that has occurred.
Another important achievement that has been made is ‘on the spot’. This term explains that police officers and investigators have different tablet PCs or notebooks in their patrol cars that can detect people, etc. They have a database and other software through which they can conduct interviews and people’s thoughts about crime and send an immediate report to the central office or law enforcement and law enforcement officials when the location of the crime is still fresh. Cellular electronics have also proven to be very useful because they can catalog, transfer, or copy evidence at a crime scene and can be managed and processed as soon as they arrive at the head of the police station. Other technologies such as crime scene detectors can copy or identify fingerprints at the time so that it allows other officers to move quickly on this issue and help the police get full access to the criminals.
Better telecommunications enables reliable and fast modes of communication between various departments of law and order. There may be sending and receiving encrypted messages so that no body except the actual recipient can read the message. Digital radio frequency is being used by the police department so that there can be easy communication even during peak hours or when the signal is jammed due to crime.
LPRT and DNA technology also contribute greatly to crime detection. LPRT stands for license plate reader technology. This technology uses OCR (optical character recognition) that captures images. This gives police officers the opportunity to track down cars or other vehicles present at the scene. DNA technology combines DNA and computer technology to combat violent crime. DNA collected at the crime scene was tested against the DNA output provided by the computer. This helps in tracking down the actual criminals.
All of these factors have contributed to the improvement and improvement of laws and detection of criminal activities to prevent criminals from these activities and warn them in the future so that the country can remain fully stable.
