NBC News apologized today for the way a 911 dispatcher’s conversation with George Zimmerman concerning Trayvon Martin was edited for broadcast last week. The edited version made it appear that the neighborhood watch captain’s decision to follow Martin in the Sanford, Fla., housing complex might have been racially motivated. Zimmerman subsequently shot the unarmed 17-year-old during a struggle. Martin’s death has resulted in nationwide protests. Following a Fox News before-and-after broadcast comparison of of the unedited and edited version, NBC News launched an investigation. “During our investigation it became evident that there was an error made in the production process that we deeply regret,” NBC News representative Lauren Kapp said in a statement. “We will be taking the necessary steps to prevent this from happening in the future and apologize to our viewers.” The segment Today broadcast last week ran as “Zimmerman: This guy looks like he’s up to no good. He looks black.” The full conversation ran as: “Zimmerman: This guy looks like he’s up to no good. Or he’s on drugs or something. It’s raining and he’s just walking around, looking about. Dispatcher: OK, and this guy – is he black, white or Hispanic? Zimmerman: He looks black.”
