Response/Opinion: Kill de sac
It is my persoanl opinion that:
1. The whole thing could have been avoided if the white collar guy had just LEFT THE OTHER FAMILY ALONE. They weren't deliberately bothering him, the kids were no more annoying than most kids who play outside, and it wasn't just HIS neighborhood, it was EVERYONE's. Out of all those neighbors, HE was the only one calling the police (bullying) on the family just because their personal lifestyle clashed with his "peace and quiet".
2. Also, the trucker shouldn't be written off as just "out of control". He spent a long time trying to mind his own business, while getting harassed by this controlling, entitled man over trivial accidents, and constantly had his family threatened. The military guy went too far, and the jury could not acknowledge that.
3. It should be noted that the trucker put more effort into trying to be friendly with the neighbors more than the other guy did. From the narrative, Military guy was the only one throwing a fit because what... "the other family was too loud", "they kept stumbling into my area", these were the same motives for the previous killers from past episodes. The only motive for this "white collar government worker's" actions is that this harmless, normal family clashed with what he deluded himself into thinking was "his neighborhood" and, if his character is the same as the show's interpretation, he was more than glad to shoot the trucker, especially when it led to the "trash family" moving out of his "perfect neighborhood". I sincerely hope the other neighbors give him shame, and the stink eye for what he did, he tore a family apart over a bunch of pointless, selfish garbage.
P.S. If anyone remembers the name of the two men involved, I like to research the victims and murderers online to see any updates.
