Shunting? Is that what this? Where am I?

So I haven't written in a while.  Things have been, well, you, happening.  And by "in a while" I guess I mean like 5 days ago.  Anyways.  I know I should jump on the bandwagon and say something about the tragedy at the Boston Marathon.  Well, I don't have words for it.  I can't understand what makes people do such things.  It also doesn't help that we don't know who did it or why they would do such a thing.  Was it to see if they could?
