And no, this story doesn't discount that.
Note that this is such a big deal that it makes the national news. These cases aren't unheard of, but they are rare enough that it's a big enough story then and there. A psycho slant-eyed bastard ate people on a Greyhound bus a few years ago: it wasn't a sign of an asian cannibalism epidemic.
So whenever you see these stories, remember they're just another form of fake news.
