Is is typical with these types of events, pretty much everything the media reported in the first few hours has been shown to be wrong.
the reporting of the 90s lead to a change in tactics by terrorists world wide.
in the 90s, a terrorist attack would be reported as a random act or accident. nothing to see here, move along. although a valid tactic by not allowing the terrorist his media exposure... it lead to chain attacks. terrorists would hit a target, wait for tv and emergency personnel to show then strike again. tough to deny the terrorism at that point.
