So is that the newest rumor or do we have an eyewitness for that???
Uncle Chip, try the "JJ Witness Video" at this site.
Starting at the 6:28 mark, you can hear a background voice (not the voice of the person shooting the video, but simply a background voice captured on the video) explaining that Brown "doubled back" on the policeman, and that he "kept on coming" as the police fired at him.
