Marathon

People from all over the world enter the Boston marathon.  They just want to run.  Yes, I'm sure they would all like to win, but mostly they just want to run.  That's why they are there.  I am trying to imagine why anyone would want to blow them up.  I can't.  I'm not accustomed to a failure of imagination but I'm stuck; I can't get my head around this.  Is it supposed to be a statement?  Of what?  I am sad and I am also angry.
