But most police agencies don’t have a full-time IA investigator, so it is often sergeants and lieutenants get tasked with that responsibility. Even for those agencies with an IA unit, it’s often the on-duty sergeants and watch commanders who are tasked with conducting the initial intake and making some initial decisions.
That’s why we offer our Internal Affairs Investigation course in two formats – an 8-hour basic primer course for every supervisor and a 24-hour comprehensive investigation course for those who want to learn how to conduct the investigation from intake through adjudication.
This course provides law enforcement supervisors and investigators with the specific skills they can use to investigate both internally and externally generated matters. This training will include directions on the crucial steps that must be taken during the intake, investigation, presentation, and adjudication phase. You’ll learn how to organize an investigation, and proven methods for conducting thorough investigations based on the latest case law.
Whether you are a supervisor with collateral duties in the initial intake of IA complaints, or you conduct full-blown IA investigations for your agency, this class is for you.
