This fact is not only painful and saddening to think about, but also says volumes for our society. Turn on any news station on any given day. One can even flip a few pages one way or another in The Mighty Signal and you will see a glimpse of evil wedged in between community events and advertisements. Right about now people go on a frantic search for someone to blame. Heard it all, seen it all before.
Scapegoats are a dime a dozen.
That's not the issue, it never was the issue, and it never will be the issue. Blaming people after the fact doesn't mean it never happened. We are far too impatient to pass the ball, pack it away underneath pretty paseos and cheerful, smoke-free environments. Security helps, but it's not enough. I can't say why people are pushed so far as to kill someone.
