Hardly a happy ending. Norgard seems to have acted like a jerk, no doubt, and he needed to be taught a lesson, perhaps, but he paid a dreadful price for his stupidity.
He got insanely drunk. He attacked someone. That person felt his life was in danger and shot him. Now he’s dead and his estate can’t sue the person who defended his life.
That is a happy ending.
Norgard wasn’t shot because he was stupid or acting like a jerk (all of which he was).
Norgard was shot because he “reach into the truck as if he was attempting to grab someone,” then “lunged again,” which actions reasonably constituted an imminent threat of death or serious bodily injury to the couple in the truck.
The perp can’t harm anyone else. Ecstatically happy ending.
He was not innocent and if he kept going after someone, his intent was to harm them. A jerk just mouths off. He doesn't try to attack someone.
Norgard deserved what he got and won't be a threat to anyone else any more.
