There was no slur. Apparently someone doctored a copy of the tape with the words "effing coons". Treyvon's lawyer stated that was not on their copy of the tape released by the Sanford police. The bogus tape has gone viral in the MSM.
As soon as I heard it, I realized that it was doctored. The rest of the call you can tell is on a cell phone but those 2 words sound like that were recorded elsewhere.
The media is really stirring the pot.
