From an article on news mistakes from the Post & Mail of Columbia City, Ind., via Testy Copy Editors:
Newspapers are not allowed to make ANY changes to an AP story, no matter how glaring it may be. It's a rule we must follow and sometimes the story with an error is the only one on the topic, and if it's important enough we have to run it.
The only exception to changing an AP story is cutting off paragraphs at the bottom so the story will fit.
