Laws are meant for regulating the society. It is usually the police who ensure that these laws are enforced. The Police prevent or solve crime, capture criminals and hand them over for trial, and protect and aid the public. In the course of these duties, the police may undertake many different tasks such as controlling traffic, managing riots, or investigating serious crimes. In times of emergency, they may be asked to find shelter and protection for victims of fires, floods, or other disasters.
Police forces are Government organisations charged with the responsibility of maintaining law and order. The police may also be known as a constabulary, after constables, who were an early manifestation of police officers.
