According to the article, she brandished her legally-owned firearm at a neighbor who intentionally rammed her car. The primary explanation given by the police and prosecutors is their policy of assuming that whoever calls the police first is the victim. In this case, that was the attacker, so the true victim will now spend two years in prison.
I thought the last paragraph in the story ws especially poignant.
The Sierra Club and Black Lives Matter have expressed serious concerns about how this case was handled. Given that it involves a legal gun owner protecting her family and her property, it would be nice to see the National Rifle Association speak up as well.
