Again: he sued for defamation and emotional distress, not libel or slander. The Poynter site has the actual complaint. I think legally he’s on pretty shaky ground, but I suspect NBC/Comcast/Universal will offer some kind of settlement rather than take it to trial. And it will take two to four years to get that far. NBC and its local affiliate edited audio that might be construed as making the guy look bad. Is he defending himself or a cold-blooded killer? That hasn’t been determined. So Comcast will probably hold him at bay until after his criminal trial. And if he’s acquitted, the defense will be the reporting made no difference. If he’s convicted, the defense…basically takes care of itself.
I seriously doubt he’ll have a case against Disney/ABC.
As far as editing audio to mislead audiences, the local NBC affiliate does it all the time, altering and truncating quotes and broadcasting stories that are rampant with errors. Even when they’re corrected, they keep them up on their website for ages. Really sad excuse for journalism.
