() - Recently, CNN enhanced audio of George Zimmerman — the man who shot Trayvon Martin — to try and determine if he did, in fact, use a racial slur while calling police on the night of the shooting. Back then, it sounded like Zimmerman might have used the phrase “fu**ing coons,” and his critics have cited it as evidence of a racially-motivated attack. But now CNN has enhanced the audio again, and the reporter is casting doubts that the term was used.
