A large part of every police officer's job is a game of crime prevention. It's hard to break it out. A front-line officer will take a call, and then while taking the police report they will speak with the victim about preventative measures. Even with our school liaison officers, a large portion of their work is preventative, but of course they're also involved in investigating crime at the same time.
It's a primary focus of policing across Canada. A major portion of our job is prevention.
