I am posting this here because the deputy involved is a PFer. I won't reveal his screen name. He actually introduced himself to me through a PM here. We later hired him.
I conducted the internal investigations into his actions. I have concluded that his actions are within policy. I wrote the policy and personally conducted the training on it. The GBI is conducting an independent investigation. While it is outside of the scope of my investigation, it is my opinion that his actions were lawful.
If you will allow me to set aside my decorum for a moment, what the video doesn't clearly show is that when he heard the sound of the pistol slide being racked, he pulled the other deputy out of the doorway, stepped around him, and engaged the threat. I am extremely proud of him. He performed his duty in the finest tradition of a Deputy Sheriff. I say that not only as his Chief Deputy, but as one of his instructors. He is Rangemaster's 63rd win. He is my #1.
The pistol is a G34 with a Surefire light. The ammo is Hornady 135gr +p Critical Duty. He fired four shots with one hit. Based upon my examination of the evidence, two of the shots went over him as he fell. Their trajectory indicates that they would have hit where he was standing. The fourth is low and to the right. I believe that it was fired as he was trying to stop shooting. I refer you to the Force Science Institutes study on stopping an action once started.
I can't comment on the wound at this time.
I will answer what questions I can.
