Summary: MANKIND SO WICKED AND CRUEL TO EACH OTHER thousands of runners still on the course, two bombs exploded at the finish line of the Boston Marathon on Monday, killing two people, injuring scores more and turning the city's most celebrated event into a grisly spectacle of shattered glass, blood and screams. Video from the scene showed people fleeing and an enormous cloud of white smoke after two blasts about 20 seconds apart. Emergency personnel carried bloody spectators away. ?We saw two big puffs. I thought maybe it was fireworks. Then it went off again. And then all of a sudden we heard people crying and running away. It was a huge horde of people just running away,? said Serghino Rene, another witness, who was a few blocks away. ?We just got away from the scene and away from tall buildings.?
