BUT THEY WON’T SAY WHO IT WAS: “Seasoned” NBC Producer Behind Edited Zimmerman Clip. I’d say “deceptively edited” myself. Perhaps even “libelously edited,” which may be why they’re keeping mum.

UPDATE: Jim Treacher: “Weeks ago, this stopped being just a story about a shooting in Florida. This is about the utter corruption of the mainstream media. Hey, it’s your reputation, NBC News. It’s been taking a beating for decades now. If this is how you want to finally destroy it, fine by us. No wonder you actually made nice-nice with Sarah Palin. You’re just that desperate to win us back.”
