An account not of post-9-11 activities, but of the shift in Britain toward intelligence-led policing since 1993. While concentrating on Britain, Gill (Liverpool John Moores U.) also compares police intelligence structures there with those in Canada, New York State, and elsewhere in North America. Among his topics are police and crime networks, targeting the intelligence process, technologies of information gathering, and informants and undercover police. He covers events up to February 2000.
