I see. And what training, instruction, or other expertise do you have to support your assertion that this was a “non lethal situation”?
I believe that I could cause a permanently disfiguring, debilitating, or lethal injury with any of the long-handled tools in my shed. I believe if a racist teenager swung one of these tools at a black man, you, too, would consider it to have been a use of lethal force.
I think a reasonable person facing a 15-year-old attempting to strike them with any of my gardening equipment would reasonably fear a threat of death or grievous bodily harm.
I reject your characterization of this as a “non lethal situation”.
