Questions over Times story about Tupac Shakur and P. Diddy

connection in fatal shooting. The Times said last week that it had uncovered new details about the 1994 beating and shooting of Shakur that involved Diddy, who has completely denied the tale. Diddy refused to talk to the reporter before the story ran. Smoking Gun says there are problems with the documents. I don't know the truth here, but I do know that there have been questions about Chuck Philips, a pulitzer-prize winning reporter, in the past. It's an editor's greatest nightmare having such a big story being seriously questioned.
Update: Times apologizes for errors.
Update II: Patterico has more details on the controversy. He is a Los Angeles County deputy DA.
