Police forces around the world engage in a variety of activities. Many of these activities, such as roadblocks, arrests, and increased police presence in problem areas, are reactive, but there are also many proactive measures involved in police work. Both reactive and proactive measures involve a large amount of information, and police officers need to understand vast amounts of knowledge to carry out their normal duties. This amount of information means that police officers also have to be proficient knowledge workers. Knowledge Management Systems in Law Enforcement: Technologies and Techniques presents the latest research and trends in using knowledge management to aid police activities. The principles and practices presented in this book will help law enforcement professionals find ways to quickly bring vast amounts of knowledge to bear in law enforcement, but will also help prepare the next generation of police officers for a more knowledge-intensive field.
