Highly experienced supervisors show you how to conduct internal affairs from incident to adjudication.

Law enforcement officers are under scrutiny like never before. That’s why when an officer is accused of wrongdoing, the investigation must be conducted by competent and professionally trained investigators. Officers deserve it and so do the public they serve. That’s where you come in!

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.

Attend this course and receive:

  • Step by step instruction on how to conduct internal affairs investigations and “leave no stone unturned”
  • Learn how new laws affect investigations.
  • Learn how to mitigate criminal, civil, and administrative liability for your officers and your agency.

Whether you are a supervisor who may one day have to manage an OIS scene, or you conduct such investigations for your agency, this class is for you.

Instead of “Death by Power Point” you’ll discuss real cases with highly experienced investigators. You’ll learn the specific way to conduct investigations, the pitfalls to avoid and how new laws affect your investigations.
