My new CJR column is on how media organizations can do a better job correcting their own mistakes. Here’s how it begins:

The most controversial media error in recent months came in a 60 Minutes report by Lara Logan about the attack on the US mission in Benghazi, which ran for more than 15 minutes on Oct. 27. Logan’s story featured claims by a security officer that were later shown to contradict his statement to the FBI. After the officer’s claims came under increasing scrutiny, Logan apologized for her error on CBS This Morning on Nov. 8 and acknowledged it had been a mistake to include the officer’s account in a brief segment at the end of 60 Minutes on Nov. 10.

….What hasn’t yet been widely appreciated, however, is the way that CBS and 60 Minutes have compounded the original mistake by scrubbing their digital files of the retracted segment. A press release issued yesterday by the Association for Education in Journalism and Mass Communication (AEJMC) called the news organization’s handling of the error “a case study in how not to correct an inaccurate report in the digital age.”
