There's 330 million people here. You, being not from here, only find out about what's exceptional, not what's normal. This case made the news because of how bad it is. It this was common, it wouldn't have made the news.
And don't me wrong, I'm certain there are millions of good people in the USA. But the assholes are in the ascendancy. Obviously.
Stand up, or get flushed down the shitter.
Again, you're being presented with this article because it is an exceptional occurrence. If it wasn't, we wouldn't be discussing it.
