Interrupted peace

I was in a discussion that included trauma in the classroom when I heard the news about the shooting in Cleveland. Once again the peace of our children and our neighbors' children has been interrupted by the banging and popping of anger and violence. What does one say to the families, friends, and fellow students of those who have been wounded? And what does one say to the family, friends, and fellow students of the who was the shooter who is now dead? Do we live with indifference because it was not as traumatic and deadly as other shootings? Do we dare be cautious and hesitant about being peacemakers out of the fear that being peacemakers may make us unwitting targets? "Seek peace and pursue it!"
