Public criminology is about using knowledge about crime and criminal justice to help make a difference in people's lives. It means looking at crime from the perspective of the people affected—the victims, the criminals, and their families—and coming up with solutions that are informed by the best available research. It could mean things like helping communities come together to make their neighborhoods safer, or finding ways to give victims the support they need to heal. Public criminology can also mean finding ways to prevent future crime or to help people who are struggling with criminal behavior.
