I could say a lot of things about these bombings, most of it along the lines of This is terrible, When is this going to end?, and Haven't we seen enough? It all seems inadequate.
This picture below, however, does not seem inadequate. It is of Martin Richard, who was killed in the bombing (and whose six-year-old sister lost her leg and mother suffered a serious brain injury), holding a poster he made in school.
It reads:
No more hurting people Peace
No more hurting people Peace
