Smith got the wrong charge. It should have been VOLUNTARY manslaughter. here is my rationale. Being fully prepared for the next illegal act by someone else isn’t a crime. it is legal to use deadly force on someone that breaks and enters your home. Pre-meditation CANNOT involve requiring someone else CHOOSING to break the law. If Smith had hunt down those kids and shot them on their lawn/walmart/cub foods then it was Pre-meditated murder.
Had he done all the preparation that he did and just plainly shot those kids dead upon entering the house then I believe he would have committed no crime.
His crime was subdueing those kids and then playing exicutioner. there is no place in society for that. I don’t care how far RIGHT you reside and I am pretty RIGHT. (and by RIGHT, I don’t mean correct).
