Odd story out of Boston... someone bombed the Boston Marathon earlier this afternoon; two are dead and another score have been hospitalized. The bombing happened a couple of hours after the winners had finished, so it wouldn't have been aimed at having too many East Africans winning the big marathons. At the 4-hour mark of a marathon, you have recreational runners for the most part.
A local crazy, maybe? An anti-patriot messing with the celebration of Patriot's Day? It doesn't smell like a jihadi, but it's likely far too early for armchair profiling.
Not only do you have downtown Boston messed up, you have hundreds of runners and their families who just had what is often the highlight of a running career ruined. Not good; prayers are an order.
