Wow! This is the first time George W. Bush has ever did something that actually stopped people from being murdered.
A confrontation was about to happen between his lead Secret Service agent and Chilean security officials. After Dubya stepped inside the complex hosting the APEC summit (a bunch of people discussing how to fleece their own citizens), the Chileans attempted to bar the US agent from entering. A scuffle ensued before Bush, displaying a courage that one would not expect from a person of his intellect, pulled his bodyguard away from the fracas and into the building.
