I agree, the woman is batshit crazy (er, well WAS), for refusing to put down the shotgun after being told to put the gun down after she pointed it at them.
Because not all of us want a body count. I'd rather people pull it and have the person flee than pull it and plant someone.
Um, Sunset in Los Angeles, California, United States for May 22, 2010 is at 7:53pm. An HOUR later, at 9pm, it was getting pretty dark by then. But I digress.
As for why the cops took an hour before they shot her, most likely they were trying to talk the bitch down.
No matter how you slice it, it appears the Census worker fucked up and the woman with the shotgun was just plain batshit stupid for drawing down on cops. Too bad she was so old, that means her defective genes most likely already have spread.
