Strong presentation and relay of information and investigative techniques. The practical examples and ability to work through cases live made the techniques much easier to understand.

I have taken Ace It, Kenny William’s class, multiple triple I solutions,Cartel Traps & Desert Snow. You take a little bit of everything from each class and incorporate what works best. Nick’s class helped me more the interview portion of the interdiction stop. I loved the amount of in car interviews and demonstrative vids of deceptive behaviors. This was well worth the drive to attend and spend money out of pocket.

Mr. Jerman was obviously very knowledgeable about the material. He spoke clearly and was very organized. There was a great deal of material covered, but he gave us enough information to follow up on the different areas. Overall it was an amazing overview of the potential investigative tools.

I recently attended Nick Jackson’s interdiction training and can honestly say it was one of the most useful and applicable interdiction classes I’ve taken. The material was incredibly helpful, engaging, and kept my attention the entire time. Everything taught felt realistic and directly applicable to what I’ll be using on the street the moment I get back to work.

The deception detection portion was huge for me and gave me even more confidence in locating criminal activity without having a K9 in my jurisdiction. I’m already looking forward to attending the full Deception Detection 2.0 course next.

I paid for this course and hotel completely out of pocket due to the distance, and I can confidently say it was worth every single dollar. 10/10 experience and I’d absolutely do it again.

Great deep dive on the behaviors of criminals. Using his personal cases to show examples of all verbal/non-verbal deception. Absolutely enjoyed class.

This class was AWESOME. Nick went into great detail about each and every step in the process of a complete and thorough traffic stop. I learned a significant amount of about identifying cars, recognizing behaviors, and the interview process. As an added bonus, I learned additional tools such as access to federal LPRs, license plate lookups, and Copart. Nick was fantastic in showing bodycam footage as well to not only talk about behaviors, but show them to the class so they could recognize them. I’ve taken several interdiction classes, and I knew this one was going to be the best. It did not disappoint and I’d highly recommend to any officer looking to advance their skillset.
