Part of the Professional Policing Curriculum in Practice series, this text covers the important contemporary topic of policing those who may have poor mental health are classed as vulnerable or at risk, which runs throughout the policing curriculum. It examines how policing has evolved when dealing with vulnerable people and covers situations such as county lines, modern slavery and online bullying and harassment. It emphasises the importance of the overall police response as part of a multi-agency approach and promotes the need for individual professional curiosity from police officers. Case studies add to the rich knowledge base provided, and critical questions and examples of evidence-based practice are included to embed understanding and help cement theory. Students will develop their critical thinking abilities and gain the confidence to recognise and deal with the complex issues associated with this topic.
