In your chicken skin suit:

on 9/11, Rudy and company had nowhere to go. Worse, they had no one to talk to. It had taken them two terms to select a new communication system to replace the city's 1960s vintage two-way radios. When they finally did, it was in a no bid contract with a politically wired supplier who sold them untested equipment.

The equipment never worked. On 9/11, all the firefighters had were radios the city had called "obsolete" and "totally inadequate" 11 years earlier. Rudy would later tell spellbound audiences that firemen in the towers ignored orders to evacuate. In fact they never received them.
Barrett and Collins found not one instance of Giuliani, Kerik, Von Essen or Sheirer issuing orders to anyone that day. But as Bush flew about the country, Rudy walked in plain sight and spoke defiantly. On those words and pictures his campaign rests.

In more technical terms, Giuliani's a lying sack of shit.
