2001-09-11 10:13 a.m.

More prominent buildings in Washington begin evacuation. The United Nations building in New York City evacuates first; many federal buildings follow later. [CNN, 9/12/2001; New York Times, 9/12/2001] Counterterrorism “tsar” Richard Clarke apparently began arranging these evacuations a short time before this. [Clarke, 2004, pp. 14-15]
