Sulc Lawrence B. Law Enforcement Counterintelligence

Varro Press, 1996. — 229 p.This slender book is more of a memoir than an instruction manual. It gives excellent examples of how criminals can penetrate law enforcement agencies. The author is bracingly honest by reminding the law enforcement community that organized crime utilizes its own agents and deception operations. This one will get you thinking about counter-surveillance and opsec, things some smaller agencies might be lax about. It is the only book I am aware of geared towards law enforcement for this topic.
