My policeman added: "It was made quite clear to me in my first few days that one's first ambition should be to get into a department." This once meant CID or traffic. Now it is a vast bureaucratic empire embracing firearms, dogs, domestic violence, child protection, burglary squad, fraud squad, drugs squad, communications and IT, accident investigation, health and safety, personnel, force development, equal opportunities, school liaison, hate crime, "managing change" - you name it, someone in the Home Office thinks the police should do it.
