Read this: Studies of this kind outside of Europe are even rarer, so it is difficult to make generalizations, but one small-scale study that compared transnational police information and intelligence sharing practices at specific cross-border locations in North America and Europe confirmed that low visibility of police information and intelligence sharing was a common feature (Alain, 2001). Intelligence-led policing is now common practice in most advanced countries (Ratcliffe, 2007) and it is likely that police intelligence sharing and information exchange has a common morphology around the world (Ratcliffe, 2007). James Sheptycki has analyzed the effects of the new information technologies on the organization of policing-intelligence and suggests that a number of 'organizational pathologies' have arisen that make the functioning of security-intelligence processes in transnational policing deeply problematic. He argues that transnational police information circuits help to "compose the panic scenes of the security-control society". The paradoxical effect is that, the harder policing agencies work to produce security, the greater are feelings of insecurity.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Where has cross-border policing been most under-studied?
outside of Europe
