 In the 1980s, Regional Information Sharing Systems (RISS) Centers, a sharing system, were introduced throughout the nation to collect and store data on criminals.The post-9/11 environment in the US, the "era of Homeland Security" for American policing, has increased demands for law enforcement to build global partnerships and to work more closely with local agencies to expand the capacity of the state to fight both crime and terrorism.Owing to the belief held by some that 9/11 and other terrorist attacks could have been prevented if not for intelligence failures, a key difference between intelligence-led policing and earlier strategies is that intelligence is no longer considered a specialized function for crime analysts or intelligence units.
