The Chief of Police, and myself, went to a home to arrest a subject that we had a municipal warrant on. While there, we encountered another subject that the state Department of Corrections had a multiple parole violations warrant for. When the Chief of police attempted to take the subject into custody, he resisted and struck the Chief. I issued commands to the subject to get on the ground but he refused to do so. I then used my department issued PhaZZer Enforcer on the subject. As soon as the darts hit the subject, he fell to the ground. Once the cycle was over, the subject yelled out loud “That was a mistake, I’m sorry!” and rolled over and placed his hands behind his back. He was placed in custody without further incident. The PhaZZer Enforcer is, in my opinion, a valuable, well built, tool for today’s Law Enforcement Officer.
