It's truly become an American obsession. Guns are advertised and sold as fashion statements where I live, and pretty much across most of the country, I think. It's unbelievably sad.
I always wonder when we have such an awesome police force why are we arming individuals, at least their mental health should be screened every few months!
I can only guess that someone who attacks concert-goers having fun wanted to hurt people enjoying their lives because he hated his own life so much.
But I have to admit this shooting has stumped me. None of the usual signs are there. From the information we have now, this seems to have come out of nowhere.
Feeling alone, isolated, angry and insignificant, in need of serious mental healthcare, living in a society obsessed with violence, given easy access to guns.
