A guy bought a shotgun, went home and killed his (girlfriend or wife), while drunk. The problem with the lawsuit was that Kmart's staff was irresponsible in their sale. When questioning the sales clerk, they asked "Did you think he was too drunk to buy a gun?"
Her response "no, but he was too drunk to fill out the form, so I had to do it for him."
(That's going from memory, so if anyone wants to correct it, so be it.)
First off it's illegal for her to fill out the form for the guy, but just the idea that someone is so drunk they can't fill it out and you still sold them a gun? Very irresponsible. It's like Lanza's mother trying to have her son committed, but not securing her weapons from him, it's just unconscionable.
