"In an ongoing search for more effective and efficient policing, police in Canada and elsewhere are experimenting with new models of police service delivery. This discussion paper explores one of these new approaches - the sometimes controversial topic of "tiered policing". It begins with a clarification of the term and the rationale or logic for this innovative approach to using human resources in policing. Tiered policing models essentially broaden the categories and types of police personnel that perform various police functions and a typology of tiered policing personal is presented: including regular police, police with limited powers, special constables, as well as, private security, civilian members and community partners. The paper examines the creation deployment of a new type of tiered police officer introduced in the UK - Police Community Support Officer (PCSO) and some innovative Canadian examples of tiered policing. The paper concludes with an overview of some of the policy and implementation issues raised by the introduction of tiered policing models."--Page 1.
