I've written about this on Twitter, and Derf has written a long essay about this situation.
Basically, in May, my friend editorial cartoonist Ted Rall wrote a blog item about a 2001 incident in which the LAPD handcuffed him for jaywalking, while a crowd formed, jeering at the police officer. The LAPD somehow got an audio recording of the 14-year-old incident to the Times, which through minutes and minutes of static, seemed to depict only a polite interaction. The Times publicly "fired" Rall (he was a freelancer who regularly contributed to the Times) because of "serious questions" about accuracy and integrity.
Ted, and apparently others, have since had an audio analysis of the recording done, and the enhanced version seems to include voices in the background saying things like "He was just jaywalking" and "You need to take off the handcuffs."
It's been over a week since Ted's provided this new evidence. I'm puzzled why The LA Times hasn't responded, and why this hasn't become a bigger national news story.
