Obama delivered a moving speech at the Boston Memorial Service on Thursday, saying, “It should be pretty clear by now that they picked the wrong city to do it. Not here in Boston.
At a Boston cathedral about a mile from the spot where two bombs on Monday ripped through the crowds at the marathon finish line, killing three people and injuring 176, Obama sought to convey strength by vowing "we will find you" to the person or people behind the attack.
A very emotional choir member broke out in tears and wept through the performance at the memorial:
The video of the crying girl in the choir has gone viral.
The bombs in Boston killed an 8-year-old boy, Martin Richard; a 29-year-old woman, Krystle Campbell; and a Boston University graduate student and Chinese citizen, Lu Lingzi.
