>> explosion downtown. >> about a third of the building has been blown away. >> the whole front of the federal building is gone. >> mcveigh is only two blocks away when the bomb detonates, but he makes it to the getaway car and heads north on interstate 35 where he is soon stopped for driving a vehicle without tags. among the items found after his arrest is a business card for a military supply store. on the back is a handwritten note, "tnt at $5 a stick, need more." >> there's no question in my mind that timothy mcveigh wanted to get caught, wanted to become a martyr. wanted the u.s. government to execute him. he left a trail of breadcrumbs for federal agents. he was seeking the deluxe suicide-by-cop execution package.
