IIRC, that bomb used nails and other metal pieces to inflict its damage. Just looked it up again: 111 were injured, 1 person killed directly, 1 indirectly. From the photo posted on one of the blasts, this one feels like it may have had more explosive power, but less shrapnel (just guessing).
FWIW, I suppose you have also reminded me that the guy who plead guilty to that 1996 incident was an anti-abortion activist.
Thanks, so it definitely appears to be a much more sophisticated attack than what occurred in Atlanta.
