One very overlooked book is, Guerriilla, by Charles W. Thayer. Thayer reminds me of a the author of, This Kind of War, by Ted Fehrenbach a soldier/scholar who was able to get down into the small details but also discuss the main overall themes. He combined both academics and actual real world experiences. He had the rare experience of working COIN from both perspectives being with Tito's guerrillas and then working with the Department of State post Army.
His page of acknowledgements of people who read and commented on the book is living history....Averell Harriman, Samuel B. Griffith, Roger Hilsman, Victor Krulak, Edward Lansdale, and his fellow cadet at that college on the Hudson, William Yarborough. The preface is by Sir Fitzroy Maclean. It's pretty amazing to read. My well thumbed copy cost me $1.45 which just goes to show that prices don't always equate to value.
On the Law Enforcement realm I would check into the products of the Problem Oriented Policing sites but bare in mind that L.E. Intel doesn't have anywhere near the depth of the Military when it comes to methodology. Plus, a lot that passes for L.E. intel literature is geared for managers and supervisors. It doesn't go into the creation of "actionable" intel that tells you what is going to happen when and where. That is very difficult without the use of various technologies and the use of informants which are both areas of concern for domestic Intel.
