Two years ago today, the ever-so-cute Dzhokhar Tsarneav planted a nail-filled pressure cooker bomb at the feet of an eight year-old boy, Martin Richard, he did not know and who had done him no harm.  It had the intended result:

The child lost so much blood, there was almost none left in his body. The Boston jihadi Tsarnaev "believed what he had done was good, that he is a Muslim soldier in a holy war against America and had taken a step to reaching paradise." 

A moment of silence, a call for kindness and the pealing of the city's church bells will be the hallmarks of Boston's events noting the two-year anniversary of the Boston Marathon on Wednesday.

The moment of silence will be observed at 2:49 ET, the time when the first of two devastating bombs went off in the crowds gathered to watch the marathon in 2013.

Mayor Marty Walsh has declared April 15 One Boston Day, beginning a tradition that organizers say is about "resiliency, generosity, and strength of the people that make Boston the great city it is."
