  John Tarr

I began my career in 1994, for the Daytona Beach Police Department.  During my career there, I specialized in DUI Enforcement and became a Drug Recognition Expert.  I was also trained in Traffic Homicide Investigations and became a lead THI Investigator for the city.  Later in my career, I was afforded to the opportunity to become one of our agency’s first officers to begin training in Crisis Intervention Training; an assignment that I was excited about due being involved in a shooting early in my career.

An injury on-duty led to an assignment in Accreditation, where I was able to help our agency receive Accreditation status and also led to me being promoted to Sergeant.  As Sergeant, I had 22 officers under me, supervised the CIT Team, and became the K9 Unit Supervisor.  I took a five year leave from law enforcement, chasing my dream job; the economic collapse ended that and I returned to law enforcement with the Edgewater Police Department.

While I was with the agency, I was asked to start their K9 Unit and became their first Canine Officer, with my partner Karma.  While with the agency I became the head of the union and chair of the pension board.  Once again, I was promoted to Sergeant and placed in charge of a squad.  While responding to a call to assist my officers, I was involved in my second officer involved shooting.  It was during this time I learned how valuable the support and motivation I had received from my first agency and the officers there had been; none of that occurred at my new agency.

I was diagnosed with PTSD and fired.  I had 19 years of total service and was not even spoken to by anyone at the agency, just HR in the city.  I applied for my disability pension, represented myself at the hearings, and received my pension.

Life has gotten a little more relaxed.  I am back to being a fishing guide, teach as elementary school as a substitute teacher, teach various law enforcement classes at Daytona State College, and still represent officers, when asked to, for internal investigations.  I have never forgotten my Brothers and Sisters on the front line, and I am always looking for ways to help them when they need it.
