Voices: Shocking rape story violated Journalism 101

The stomach-churning story led to a police and university investigation, student protests, a temporary ban on fraternities and sororities at the school — and, eventually, tremors in the media that dared to ask: Was the account to be believed? Sixteen days later, another bombshell: Rolling Stone backed off the story.

On Friday, the magazine said it discovered new information that made it lose faith in the piece, days after reporter Sabrina Rubin Erdely defended it.
