Reports coming in from Boston are describing the deadly bombs as devices similar to the Weather Underground nail bomb that exploded prematurely in 1970, killing three of Ayers' terrorist friends. That device was intended to be detonated at a soldiers' dance at Fort Dix, New Jersey.
As for yesterday's tragedy, one man had 37 nails removed from his legs.
