Attorney General Mukasey was roughly twenty minutes into a speech defending the administration's torture policies and particularly arguing against prosecutions of people who made decisions in the aftermath of 9/11 (essentially arguing against what he believed amounted to the criminalization of policy differences).
Some seven or eight minutes prior to the incident a heckler start shouting, calling Mukasey a "tyrant." But the AG seemed unfazed by this; and members of the audience shouted the heckler down.
The eyewitness tells me that Mukasey seemed particularly in earnest about the argument he was making. And when he first began to falter it appeared he was merely choking up. Soon, what at first appeared to be choking up blended into slurred words. Twenty to thirty seconds later he collapsed, his fall broken by a nearby FBI agent.
It was apparently a fainting spell, so yes, I can make fun of it.
