Not only today's news on shooting

As I was watching the news a while ago, breaking news appeared on my screen. Another school shooting, this time in in West Lafayette, Indiana, the next door state. It is happening right now, so I don't have many details yet.

What I have information on is that according to Wikipedia there were 14 school shootings in 2013, and already 5 (including this one) this year! Five! - in 3 weeks!
I wonder what is wrong with this country. There have been many heated discussions regarding gun issues but in my eyes, no matter how you look at it, something is definitely not right.
