From a quick glance over at Newseum.
New York Daily News: We Bag The Bum!
Miami Herald: Facing Justice
Houston Chronicle: 1 Down, 1 To Go
Several papers: Caught or Captured
Several papers: 'Caught Like A Rat'
The clear favorite: 'We Got Him' or 'Got Him'
Interesting to see how these trends emerge in newsroom working independently. I like how the Chronicle sets the news in a broader context. The Caught headlines work too, especially if paired with big pictures of Saddam.
On such days, though, quotes often double as display headlines. The last two clearly resonated.
