Easily explained to LE, especially when he has more than 1 witness... "I feared for my friend's life and thus used necessary force to prevent serious bodily injury." Open and shut... I too have seen what damage a bat can cause to the cranium, it is not pretty. Even if you survive the initial blow there can be extensive damage and long term injury. I have a very delicate case on my hands when it comes to self defense... I suffer from Cervical Spine Rediculopothy (I had a neck injury that led to the surgical removal of one of my C-spine discs and now I have "equipment" connecting two of my vertebrae), TBI and PTSD, I have a very viable reason to defend myself from potential serious bodily injury, one wrong move and I could be either dead or paralyzed and I have every right to prevent this from happening caused by any altercation.
