The ANP have not gone away, but maybe before they do Hurst have published 'Policing Afghanistan: The Politics of the Lame Leviathan' by Antonio Giustozzi and Mohammed Isaqzadeh.

The publishers blurb:
This book is a rare in-depth study of a police force in a developing country which is also undergoing a bitter internal conflict, further to the post-2001 external intervention in Afghanistan. Policing Afghanistan discusses the evolution of the country’s police through its various stages but focuses in particular on the last decade.

The authors review the ongoing debates over the future shape of Afghanistan’s police, but seek primarily to analyse the way Afghanistan is policed relative to its existing social, political and international constraints. Giustozzi and Isaqzadeh have observed the development of the police force from its early stages, starting from what was a rudimentary, militia-based police force prior to 2001. This is a book about how the police really work in such a difficult environment, the nuts and bolts approach, based on first hand research, as opposed to a description of how the Afghan police are institutionally organised and regulated.
A review by a British academic, Alice Hills:
This is the first serious, comprehensive and convincing account of how policing in Afghanistan really works. Giustozzi and Isaqzadeh’s impressive study of the political dynamics of Afghan policing extends the police-studies agenda and is essential reading for anyone interested in the political economy – or reform – of policing.
