I didn't mean the content, just the headline. Every other one I've seen use the 'Bush Offers Best Wishes for Clinton' headline. The Boston page had it as you posted, 'Audience boos as Bush Offers Best Wishes for Clinton'.
I think someone at the Globe wanted to make sure people noticed that.
The links in post 44 all have the "audience boos" headline, so you can infer it's an AP piece that sites take and repost without using any editorial judgment whatever. "Hey, if it's the AP, it must be true".
But the Guardian which you linked to has the other headline, but the body has the line about booing and nothing being done about it. And we can all guess if the Guardian will be the last to remove the story, if at all.
