The Daily Recycler has the very cool video of President Bush rescuing the Secret Service agent.
According to the newspaper story, Chilean security had been giving the Secret Service grief all day.
If I'm understanding the sequence correctly, one agent got roughed up but didn't resist and ended up out by the limo. The other agent raised holy hell, and this is the one the President waded into the fracas to get.

You're not stopping this guy
UPDATE:
Here's another copy with English audio. "You're not stopping me!"
UPDATE II:
The agent's name is Nick Trotta. His old high school has a webpage for him. He is the son of Italian immigrants and very religious. It was a priest who put his name forward to the Secret Service, as he found out later.
It's clear he's everything a Secret Service agent should be. For a while there, I think he was the only protection the President and First Lady had.
