Do you think that disarming a boy with a pitchfork requires use of deadly force? Maybe if a soldier was down and the boy was standing over him it would qualify. Absent that, it's murder. I hope we see further descriptions, maybe videos, of this encounter so we can see what it was. BTW, a shot to the heart is tough to pull of if one is being attacked; it's quite easy for a trained shooter from a fixed position. The other boy was hit in the head. Think about it.
