Knoxville Police Department

The Advanced Criminal Investigation and Interview & Interrogation Case Law courses facilitated by John Cajacob were great. Mr. Cajacob presented the material in a way that allowed everyone in attendance to not only understand, but able to apply what we learned to the job. The case law course should be a mandatory requirement for all police academies.`

I have been a St. Paul Police Officer since 2014, and I have been a licensed Police Officer in Minnesota since 2008. I am also a licensed attorney and member of the Minnesota State BAR. I graduated from of the University of St. Thomas in 2005 and the University of St. Thomas School of Law in 2009. I believe that my legal education and teaching experience, as well as my work experience as a Police Sergeant in the state of Minnesota, makes me an excellent candidate for an instructor position at Blue to Gold Law Enforcement Training.
