Thanks for your response. Hence, the inquiry. I think distance will be a make or break for this case. It will be a forensic case...
Of course if the punk was pounding Zim’s head into the walkway, he would have been doing it straight arm, not huddled over Zim.
So that puts his torso above Zim by a foot or more, a bullet goes through Zims clothes, through punk hoodie and clothes, maybe even through a pack of “skittles” and takes punk out. Bullet didn't have the velocity to make it through punk's body, maybe because of so many impediments in the way.
Perhaps we should channel JFK to find out the trajectory of the magic bullet that took him down.
