The only reason the tower didn't fall in '93 was because a New Yorker was illegally parked and the van with the bomb couldn't get up against the central support column. Could only get within 8 feet. They tried, folks. They tried HARD. And they learned lessons. In 1995, when they blew up the Murrah building in Oklahoma City, they had two men in blue jumpsuits hold the parking place in front of the building for mind-control victim McVeigh. 12 surveillance tapes were seized by the feds and never shown at the trial, because the tapes show others involved in the bombing.
