George Zimmerman has reportedly told his lawyers that he whispered “punks,” not a racial slur, before he shot and killed Trayvon Martin on Feb. 26 in Sanford, Fla. Earlier reports from audio of the 911 call had some claiming that Zimmerman used a racial slur, but forensic audio experts agreed that the word was “punks.” CNN independently reviewed the high-quality audiotapes, but could not reach a consensus on the word or phrase Zimmerman used.
