The first essays lay out some of the intelligence techniques that have proven effective in either Law Enforcement (LE) or the Intelligence Community (IC) and that might be useful to exchange and apply. They are followed by essays that point out some of the difficulties inherent in integrating the two communities. We conclude with a few abstracts of recent work done at the National Defense Intelligence College on other aspects of this topic. The bibliography is a compilation of key sources from the authors' works but is by no means exhaustive.
