I agree with most points except the latter. Premeditation can be formed in an instant, and in the US the prosecutors often emphasize that point. I don't think 3 of the 4 shots or ll 4 shots hit Reeva the purported intruder without conscious aiming. For all of OP's enthusiasm for the gun range, shooting watermelons and through the roof gun "wartime" flashbacks or other triggers weren't in play. He shot to kill or maim imo and that is premeditation.
he might not be convicted but that is my :cow:
I'm very familiar with what constitutes premeditation in the US, less so in SA. I agree its most likely that OP shot to harm or maim. Whatever his level of fear or anger was , I don't think that trumped his great familiarity with guns.
I don't think he knew Reeva was in there. I do think he felt justified in seriously harming the intruder he thought was there. I don't believe he formed the intent to kill as he shot, but do think he should be held fully accountable for his reckless disregard of the life of whoever was behind that door.
