In Glasgow, street gangs have existed for decades, with knife crime becoming a defining feature. More than a decade on from Deuchar's original fieldwork, this book explores the transitional experiences of some of the young men he worked with, as well as the experiences of today's young people and the practitioners who work to support them. Through empirical data, policy analysis and contemporary insights, this dynamic book explores the evolving nature of gangs, and the contemporary challenges affecting young people including drug distribution, football-related bigotry and the mental health repercussions emerging from social media.
