Despite the fact that I think you understood what they were saying perfectly fine, you can substitute "killing someone" (or "taking another life", etc.) for "murder" in their above sentence if it helps you.
I think I see your point. However, if the original poster didn't intend to substitute the defense motive with assault, then they could have made the substitution for us.
What methods are you referring to? Pepper spray? Aiming for the leg?
> that do not involve murder.
By definition if one is defending oneself, one is not committing murder.
