Patterico caught the L.A. Times with their hands in the proverbial cookie jar. He is showing evidence of an LA Times Airbrushing of it's web version of an article correcting a substantive error without issuing a correction so far. Read the post and see the scan of the print edition with the original error.
The recently issued L.A. Times ethics code states: “When we make mistakes, we quickly and forthrightly correct the record.” (My emphasis.) Yet the paper has just surreptitiously fixed a substantive error in the Web version of an article — without acknowledging the error that ran in the print version.
