Very knowledgeable and articulate.

This class has a lot of good information, I learned a lot.

Easily the best class I’ve taken. Just wish it was longer!

John had an amazing grasp of the subject and his instruction help us engaged and made points that will help my own instruction and career for years to come.

Instructor is great and very knowledgeable. He keeps his audience engaged by adding visual aids and real life scenarios of what police officers face on a daily basis. I will definitely be attending another one of John Wiehn’s classes.

Opened my eyes to new knowledge. Really broke down the 4th amendment and how to bring it back to the working day
