Next month, the city of Baltimore will have its primary elections, and a key focus of all of the mayoral candidates has been to reduce crime. Ralph Taylor, a criminal justice professor at Temple, offered some context on the evolution of crime fighting in Baltimore over the last 30 years. "Police have innovated in a lot of different ways over the past three decades, and they will continue to do so, because they are in a situation with fewer resources and more difficult challenges," he said.
