Wow. That is pretty horrific. But why are they so close!? I say that as someone who has disarmed three knife wielding suspects in 17 years. The worst was when I grabbed the knife hand of a man that was spitting his throat. He was in the driver side of a vehicle, had tried to drive through a fence into a highway when i jumped on his hood. I was prepared to jump off should he advance, but I wanted to try and talk him down. After I grabbed his hand, a fight ensued as he tried to use the knife. I took a cut across the knuckles and was able to get the knife off of him. He then tried to put the car into drive repeatedly until an officer broke his arm with a baton. I had to call my wife, who was pregnant with my oldest child, and tell her what happened and try to keep her, and myself calm while undergoing aids and hep c testing for six weeks. Another man had attacked someone with a machete in a crack house. I tackled him from behind and the machete hit the floor and we landed on it. It scalped him and took a nice chunk of dredlocks with the fist sized slice from his forehead. Now that I have kids, and I am older, I will not casually risk my life in such scenarios. But back then, I was the defensive tactics instructor and taught knife defense, so I always felt a need to “lead by example” and as I mentioned earlier, I have a high horse i get on about UK police disarming knife suspects without guns, and I’ll be damned if a Brit outdoes me-just kidding, I respect the hell out of the way they do it over there.
