This past week we passed the 10th anniversary of the day when an obviously deranged young man wielding a weapon of war massacred 20 little children and six of their teachers at Sandy Hook Elementary School in Newtown, Connecticut. We had had mass shootings before. But this time it felt different because the victims were so little and so many, and because President Barack Obama so eloquently, and tearfully, spoke to the nation capturing our collective grief and the resolve that “our hearts had been broken” too many times and that something must be done to end the killing.
