Go look again? How in the hell can you “look” at a recording?
I heard the 911 tapes that were released. And there were no racial slurs used by Zimmerman. If you have links to the recording that shows a slur being used then please provide a link.
Said under his breath right before the point where the dispatcher asks if Zimmerman is following, he says "Yes", and the dispatcher replies, "OK, we don't need you to do that."

What do you think he said? How many times will the jury replay it?
