This month the Global Law Enforcement & Public Health Association (GLEPHA) published a series of reports as part of the ‘Envisaging the future of policing and public health’ project, covering a range of topics including violence prevention, mental health, and policing marginalised communities; in the first in a series of seven articles, Policing Insight’s Thomas James looks at GLEPHA’s report on diversion, defection and referral programmes, including examples from the UK, US, South Africa, Italy, Vietnam, Belarus and Ukraine.
