It's easy to get angry and emotional about the horrific events at the Boston Marathon. In the immediate aftermath of the blasts that killed three and injured more than 140 people, the temptation to seek answers, to find someone to blame, some way to explain a senseless act of violence, often overrules our ability to be compassionate, helpful and empathic. I am not asking people to put aside all emotions -- that would be impossible. But in the wake of this tragedy, before you ask "who's to blame?" ask instead: "How can I help?"
