Technology has changed the way we live and work, and it has also affected how police departments throughout the world operate. A hundred years ago, investigations would have been conducted by detectives using their judgement and little else to solve crimes. Today, a dizzying array of tools provide more effective ways to trace and arrest criminals. Computers have enabled the creation and searching of massive databases containing fingerprints, biometrics, DNA, and other information. Computers can also be used to identify areas where criminal activities are likely to occur by mapping locations and analyzing the patterns that result.
Communications are another area where technology provide an edge to law enforcement. In the past, police officers might have two way radios or access to call boxes, but now information is at the fingertips of officers, who can quickly retrieve licence plates and driving records. Dispatch centers have become more efficient and are able to monitor larger areas with security cameras, drones, and other devices. Officers are also better able to withstand attack, with the development of effective body armor and other gear designed to defend them.
Finally, the role of law enforcement officers has also changed with technology, with new roles such as forensics specialists, toxicologists, and crime scene investigators. Readers interested in law enforcement will appreciate the tools that can be used to fight crime.
