This might get lively
George Zimmerman to sue NBC over editing his 911 call audio. The network took audio where he was saying it looks like this guy is up to no good, the 911 operator asks if he's white, black, or hispanic, he replies he looks to be black, and edited it into it looks like this guy is up to no good, he looks to be black. Normally the media has a LOT of first amendment protections against suit, but this situation might get past all those. Clearly, it had knowledge of what the audio actually said, and someone changed it to make it more sensational, and negative for Zimmerman.
UPDATE: I know something of defamation law, having won what their attorney said was the only verdict a major TV station here ever lost. A news outlet cannot make a person a public figure, and then plead his public figure status in order to gain the constitutional protections associated with that. The plaintiff must himself have gained such status. But there would be a decent argument that Zimmerman became a public figure by involvement in the fight. In any event, the audio was clearly doctored, so *someone* working for NBC had actual knowledge that it was untrue.
