How Can Computer and Internet Help in Law Enforcement?
The new century has started with a milestone in the development and technology. With the increased popularity of internet functions, cyber crime and theft have emerged as a new propaganda. Apart from online crimes, the computer technology has enabled criminals to break the law and order force with the help of sophisticated instruments. Thus, there had to be the inclusion of computer and technology in the law and order force. Now, developed countries like UK, USA, Germany, France, China, etc. use the scientific instruments such as CCTV cameras to detect the criminal forces. This has become possible only with the introduction of computers. Computers surround all the spheres of a human’s life.
Virtual reality has been a mile stone in the law enforcement. Virtual reality is like a 4D film in which you feel almost as near to the original scene that has happened. This helps during the case solving in a court where the witness tells the scene of the crime in as much detail as he saw it and it is being projected on the screen to match the original scenario that has happened.
Other important achievement that has been made is ‘on site’. This term explains that the police officers and investigators have different tablet PCs or note books in their squad cars which could detect the people, etc. they have databases and other software through which they could carry the interviews and thoughts of people about the crime and send immediate reports to the head office or any law and enforcement controlling official when the scene of the crime is still fresh. Mobile electronics have also proves to be very use full because they can catalog, transfer or copy the evidence at the crime scene and can be managed and processed immediately after it reaches the head department of police station. Other technology like crime scene detectors are able to copy or identify the finger prints at the moment thus enabling the other officers to move fast in the matter and help the police gain full access to the criminals.
Improved telecommunication have allowed reliable and fast mode of communication between different departments of law and order. There can be sending and receiving of the encrypted messages so that no body except then the actual receiver can read the message. Digital radio frequencies are being used by the police department so that there can be easy communication even during the peak hours or when the signals are jammed because of the crime.
LPRT and DNA technologies have also contributed a great deal to the crime detection. LPRT stands for license plate reader technology. This technology uses OCR (optical character recognition) which captures the images. This gives the opportunity to the police officers to track the cars or other vehicles that were present at the crime scene. The DNA technology combines DNA and computer technology to combat violent crime. The DNA that is collected at the crime scene is tested against the output of DNA given by the computers. This helps in the tracking of the actual criminals.
All these factors have contributed to the betterment and enhance of the law and detection of criminal activities to discourage the criminals from these activities and warn them in the future so that the country can remain stable entirely.
