There was more video here in this posted link than what I saw originally and I like the fact it showed more of the beginning with less editing.
The problem here is no one tried to deescalate the situation- this was 2 bulls in the ring running on emotion and testosterone, bleeding was inevitable. Crazy dead guy was already in a heightened state of berserk-ness, he was going to end up in a physical confrontation by any means yet incapable of assessing his odds which were not in his favor. His adrenaline rush overtook rationality and he lost. I give him the blue ribbon Darwin award on this day and accepted the room temperature challenge. As for the law or legality? this one's up to the jury and we shall see.
End of the day? dipshit is dead and inbreds go to prison and this community comes out on top as the trash took itself out.
In closing, you would have to be non-human to not feel for the wife and the kids to see their husband/father killed in front of you. The end with her screaming and crying has to grab anyone's emotions, it felt terrible to hear that. Who knows, maybe he was a good father and husband even if he was an idiot.
I wouldn't want to be in this jury, there's a whole lot going on in this video to argue a lot of different opinions so it's going to come down to what are the laws and what is perceived as a threat. It will be a teaching moment in the end but unfortunately for these type of people, you weren't ever going to teach them much.
The only victims here are the children and I agree with a lot of stuff up here, especially that the wife didn't work the situation harder. I think if she had gotten her stud muffin out of there, gave the video to the police and let the system work was the only out- but studly there was incapable at this point of rational thought.
