Obama vows to 'kill Bin Laden, crush al-Qaeda'

NASHVILLE, Tennessee (CNN) – "We will kill Bin Laden, we will crush al-Qaeda," Barack Obama said Tuesday as he faced John McCain in their second head-to-head presidential debate.

McCain responded in equally strong terms: "I'll get him. I know how to get him. But I am not going to telegraph my punches as Sen Obama did."
