From Law Enforcement Intelligence: A Guide for State, Local, and Tribal Law Enforcement Agencies:
"One of the recommendations of the National Criminal Intelligence Sharing Plan is that every law enforcement agency, regardless of size, should develop an intelligence capacity."
This document was written by Professor David Carter at the School of Criminal Justice, Michigan State University.
It discusses methods of gathering intelligence in the communities they serve for all branches of local law enforcement, as well as advising on the new concept of "intelligence fusion" which is the sharing of intelligence gathered on civilians by local law enforcement. It discusses the risks of trespassing on a citizen's civil rights and how to mitigate those risks while still gathering and maintaining effective intel.
It discusses methods of intelligence gathering such as dumpster diving, informant information, banking transactions, wiretaps, and CCTV videos and how to link all those different sources of intel into "actionable intelligence".
Never before has the American citizen been under such scrutiny by his government. Never before has a government had so many tools at its disposal to monitor, track, and isolate potential dissenters.
