There have been no significant developments in the investigation of the Boston Marathon bombing, and that in and of itself is noteworthy.
No terrorist group or domestic fringe organization has stepped up to claim responsibility for the attack — but the information about the nature of the explosive devices used establishes that the bombs were carefully constructed to achieve maximum carnage. The bombs apparently were built in pressure cookers and were loaded with ball bearings, nails, and other metal objects, and much of the damage to the innocent people nearby was caused by the effects of the intentional shrapnel. The death toll from the blast now stands at 3 — including an 8-year-old boy — and more than 170 were wounded. My heart aches for them and their families, and I know that my feelings in that regard are not unique.
What would motivate a person to build bombs that would tear off the limbs of random, unlucky people who just happened to be in the vicinity when the bombs exploded? It’s hard to imagine that even the most disturbed domestic group would think that injuring participants in the Boston Marathon would win converts to a cause, or make a meaningful statement about an issue. Even accepting that the targets of terrorist acts are selected through a twisted, hateful analysis, why would the Boston Marathon even be considered? How would an event that features everyday people running through city streets be viewed as a suitable object for an attack?
We need to find out who did this, and why.
