They should do a survey having the 12 year old pict and the 17 year old picts and a few of non trayvon people. Ask people to point out the correct pict of Trayvon that is closest to his death. Bracket it with questions on how closely they followed the trial. If they think zimmerman was guilty etc. Then publish those results. That will neutralize the propaganda.
Are there any polls out that shows what percentage of Americans support the verdict? If it’s more than 50% I doubt they’ll ever show it unless they can spin it.
