The bombings in Boston remind us that first responders often mean the difference between life and death. In the midst of the worst kind of chaos, first responders jump into action immediately following our darkest moments - often times risking their own lives for others. The work of all first responders should be commended. First responders deserve our unending thanks every day. As the investigation into yesterday's attack continues to unfold, I continue to send my thoughts and prayers to the victims, their families and everyone impacted by the Boston Marathon bombings.
